Pentagram of Venus[edit]

   At User talk:Fuzzypeg#Pentagram of Venus i communicated in more detail to the contributor of the most recent version of Pentagram#Pentagram of Venus about my concern that that section needs to become an independent page (and be linked from the Pentagram article). You also may want to consider commenting at Talk:Pentagram#Omnibunstrosity.

Hi, I found your images. Great. WHat software do you use ? I have made similar images as a description of rotation maps. The source code you can find at the image page or here - newest version. Have a nice day. --Adam majewski (talk) 15:45, 14 January 2016 (UTC)

I wrote my own 2d geometry editor in Java, and scripting access via JavaScript. Sometimes I'll use Inkscape also for SVG post-processing. Tom Ruen (talk) 02:20, 15 January 2016 (UTC)
p.s. You should use attribute grouping, like <g style="font-family:Arial; font-size:20; stroke:#FF0000; fill:#FF0000;"> ... </g> for your SVG common elements. Tom Ruen (talk) 02:25, 15 January 2016 (UTC)

Thank you.[edit]

I noticed you've been an important contributor / author for the articles on Platonic and Archimedean solids. I wanted to thank you for the images and information you've contributed, and also for being good at guiding newcomers. We need more like you. Thanks. -- (talk) 03:45, 25 January 2016 (UTC)

You're welcome. It's been my privilege to help here. Tom Ruen (talk) 03:49, 25 January 2016 (UTC)


I understand you are passionately in favour of including those books, but you are wrong to say that the default is the status quo. All content likely to be challenged, must be discussed and gain consensus. Anything else would be a POV-pusher's charter. All anyone would have to do is drop some crap in an article, then forever after they can claim it's the status quo. I find it disappointing that you are so insistent on promoting these books. Guy (Help!) 16:39, 2 February 2016 (UTC)

My passion is context. If people are using a name "flower of life", I think it is pointless to try to hide the source, however passionate you are to hide things you find offensive. Tom Ruen (talk) 16:41, 2 February 2016 (UTC)

Your file File:4 21 t0 E8.svg

Well its amazing. I'm working on a revised standard model of particle physics. Your file fits I think. Every red dot is a particle. Does that make any sense to you? — Preceding unsigned comment added by Lucky1111111 (talkcontribs) 20:24, 4 March 2016 (UTC)

That's an exceptionally simple theory of everything. Tom Ruen (talk) 22:04, 4 March 2016 (UTC)


Hi Tom, There's an article in NewScientist that I thought you might find interesting. nagualdesign 13:09, 7 March 2016 (UTC)

Nice! Too bad they didn't use the newest one. And now I know your name. I hope the pretty graphics help the astronomer's imaginings going long enough to find the real thing! I wish they'd not raise our hopes so much! A few months!? If its real, I'm betting we'll find it in dozens of existing photos, once we back-calculate its orbit. Tom Ruen (talk) 20:05, 7 March 2016 (UTC)
Would you like to put an imaginary wager on when they'll find it? I'll bet you a i£1,000 that it won't be this year. nagualdesign 20:53, 7 March 2016 (UTC)
No, I think we're on the same side of that bet. I like sure thing bets myself. My favorite ironic scenerio is that the pattern is coincidental, and we eventually confirm that by finding hundreds of other outer bodies in more randomized positions, BUT perhaps there really is something big, lurking in the darkness that we'll find by accident, because of this newest search for planet 9/X.

Planet Nine Path through Orion[edit]

The GAN is asking for more specific info about the chosen path. Is it the mean, the median, the line of best fit? Please let me know. Thanks. Serendipodous 10:46, 14 March 2016 (UTC)

The path given represents the position and path shown in the Artistic conception [1], and the same as shown in our version of it. That is, the exact opposition position in the sky of the sun in the artistic image. I admit a better diagram might show a full set of simulated paths, similar to diagrams here [2] although it looks like none of those are pure RA/Declination plots. There is a full sky RA/Dec plot in this video/time, [3] showing the paths (sinusoidal gray areas) and Mike Brown points out that Orion is where it is most likely now. I can't remember if I've seen such a plot exactly, but it would be hard to reproduce. Mostly I thought my simple image would help convey a sense of approximately where it might be, and how it would be moving. A better version would show a wide gray area of varied orbits.

March 1932 lunar eclipse Rating[edit]

I rated the page March 1932 lunar eclipse as a stub and of low importance. (talk) 16:44, 4 April 2016 (UTC)

I maybe found the symmetry of...[edit]

...Gyrated triangular prismatic honeycomb and Elongated alternated cubic honeycomb. Would you verify these? --Nikayama NDos (talk) 13:03, 4 June 2016 (UTC)

Hi Nikayama NDos, looks like a worthy guess. They are legal Coxeter notation, correct as subgroups of [4,4,2,∞]. I don't have any sources for the gyrated or elongated forms for 3D. The only "safe" ones I can do are pure Wythoff constructions or alternations since those are extracted directly from Coxeter diagrams. It would also be useful to get International symbol space groups for all of these. Tom Ruen (talk) 17:50, 4 June 2016 (UTC)

Ed Whitlock[edit]

I am not sure if I am following the correct protocol, I'm not an expert. I have a couple of concerns about the edit you did to the page for Ed whitlock recently. I. For the the M65 marathon record you have selected my best time for that age group correctly but then that appears on the page as a world record, which is incorrect, the record holder is Derek Turnbull 2:41:57. 2. You list my recent time for 1 mile on the track M85 as a world record. While this time is superior to the existing record it has not been ratified. As a general principle I don't think records should be attributed on Wikipedia until they are ratified and particularly in this case as there is considerable doubt it will be accepted because of track certification issues. I have greater confidence that another mile race I ran 3 days later will be accepted although in a slightly slower time. I appreciate what I think must have taken a fair bit of time to do the edit. Ed 04:00, 20 June 2016 (UTC)366EWBW (talk)

I replied here Talk:Ed_Whitlock. Tom Ruen (talk) 15:50, 20 June 2016 (UTC)

Again Tom I'm not sure if I am doing this right, if not my apologies. In your latest edit to my page you have put my recent 5000m in as a road record it was in fact on the track. The performance will need WMA ratification before it is official, similar to the mile. I think it is best to wait until the records are ratified before posting but if you think otherwise I'm OK with that as long as it is noted as pending.

"Completely characterized"[edit]

Hi Tomruen,

At complex polytope I added the sentence "The regular complex polytopes have been completely characterized" to the lead. I know that this is true for their symmetry groups (the Shephard groups), but I wanted to check that you believe it is also true for the regular polytopes. (My interest here starts with the reflection groups, and I don't actually know that much about the polytopes themselves.) And (if my understanding is right) the tables you've created cover most (all?) of the exceptional examples that are not part of the infinite family. Does this sound right?

Thanks, JBL (talk) 23:22, 27 June 2016 (UTC)

I'm appreciative for your efforts. Yes, all the real regular polytopes arise from linear diagram Coxeter groups, fully enumerated. The tables include all the finite regular complex polytopes to C4, and yes, just 3 infinite series families above that, Coxeter calls αn for real simplex, and generalized hypercube/cross-polytopes: γm
, βm
. Coxeter has one more table of complex regular honeycombs, finite set except 2 families δm
, and 2{4}r{4}2. Tom Ruen (talk) 23:39, 27 June 2016 (UTC)
Great, thanks! And thank you also for all your work on the article! --JBL (talk) 23:43, 27 June 2016 (UTC)
p.s. Is this you? I live in Minnesota too. Tom Ruen (talk) 01:35, 28 June 2016 (UTC)
Small world! :-) --JBL (talk) 01:52, 28 June 2016 (UTC)

Quarter hyperbolic honeycomb table listed at Redirects for discussion[edit]


An editor has asked for a discussion to address the redirect Quarter hyperbolic honeycomb table.

Video games with hyperbolic geometry[edit]

I recently have found that there are ones already... Maybe they should be linked into wikipedia articles, but I don't quite understand where. Alliumnsk (talk) 04:44, 4 July 2016 (UTC)

I can't say. I assume you mean video games that don't already have Wikipedia articles. If they have an article you could link at Hyperbolic_geometry#See_also Tom Ruen (talk) 05:55, 4 July 2016 (UTC)
I don't know any with Wikipedia articles, but this is very cool! Double sharp (talk) 14:43, 4 July 2016 (UTC)
If we're not just talking games, there's Jeff Week's . The Not knot movie from the 1990s was the origin of that. Tom Ruen (talk) 19:23, 4 July 2016 (UTC)

Broken diagrams?[edit]

Hi Tom,

Something funny is happening with some of the Coxeter-type diagrams on the complex polytope article -- as you can see in the image (click to embiggen), many of the diagrams are breaking into multiple lines.


On my current set-up, this happens on the tables in the following sections:

  • Enumeration of regular complex 4-polytopes
  • Enumeration of regular complex 5-polytopes and higher
  • Regular complex 4-honeycombs

I've also seen the behavior on other systems (mobile, different browsers, etc) but I don't know if in exactly the same places. Do you have any idea how to fix this?

Thanks, JBL (talk) 22:18, 8 July 2016 (UTC)

Hi Joel, yes, basically the table is too wide for your display. Ideally the graphic sequences wouldn't break like that, but I'm not sure how to change that. I've been making some of the tables less wide to help. Tom Ruen (talk) 22:26, 8 July 2016 (UTC)

3rd stellation of icosidodecahedron, pentagon facets (stellation diagram)[edit]

(Regarding one of your images on the page List of Wenninger polyhedron models)

(List of Wenninger polyhedron models - stellations of icosidodecahedron) — Preceding unsigned comment added by 20J92 (talkcontribs) 21:49, 12 August 2016 (UTC)

I've been using your images there to stellate icosidodecahedra, but I realized that the aforementioned stellation diagram was incorrect.

I want to correct it, but I'm not sure if it's permissible to upload screenshots from Sketchup (which is the software I use for polyhedron stuff), and besides, the quality wouldn't be consistent with your other images on that page.

Edit: Also, the 17th stellation of the icosidodecahedron, triangle facets, should be red instead of yellow.

Thank you very much for creating those stellation diagrams, by the way. They've proved invaluable (that's good) to helping me understand stellations.

Regards, 20J92 (talk) 09:01, 10 July 2016 (UTC)

Which images specifically? The images were made from this applet at, if you'd like to check there. It's possible stellations were wrongly selected. Tom Ruen (talk) 12:02, 10 July 2016 (UTC)

This is the image currently on the page (3rd stellation)
File:Third stellation of icosidodecahedron pentfacets (new).png160px
This is what the diagram should look like
Also, the stellation diagram for the triangle facets of the icosidodecahedron's 17th stellation. (The placement is right, but they should be red instead of yellow.)
My browser won't let me run the applet, so I don't know where the error originated.
Regards, 20J92 (talk) 00:28, 24 July 2016 (UTC)
Sorry I didn't reply. I'm not sure where the errors are. Magnus Wenninger's book Polyhedron Models, should be the standard, unless there's an error there also!? Bulatov's applet might also be a source of error, and it might define things differently. Tom Ruen (talk) 21:53, 12 August 2016 (UTC)


Tom, if you want to mess substantially with my images on the Commons, please upload your own alternatives and do not abandon my own intent. Thank you. — Cheers, Steelpillow (Talk) 13:29, 10 July 2016 (UTC)

Your request is unclear. Are you saying I should make copies and remove your version from an article? Can you tell me what's wrong with my changes? I belived they added clarity. Tom Ruen (talk) 13:35, 10 July 2016 (UTC)
I am saying, if you wish to upload a substantially altered version to the Commons, do not do so as an update to the original, but instead upload it as a new image. I posted here because your Commons talk page advised me to.
The image to be used in any Wikipedia article is different issue, but while I am here I can say that the warnings remain about drawing lines or colouring in plane regions which are not in themselves structural elements of the figure depicted: that has to be done as carefully and as minimally as possible in order for the supposed added "clarity" not to add to the common misconception instead. For example the criticism I made of your perspective projections applies - no drawing should emphasise both the lines and the plane regions as the end effect is to present a bounded real polygon to the eyeball, precisely the effect we need to avoid.

Facet defining equations of regular dodecahedron[edit]

If the facet defining equations should describe a dodecahedron with cartesian coordinates given in the paragraph before, I suppose they do not have the right scale! It can be easily checked that the distance of two parallel planes described by these equations is and the edge length . However faces of a dodecahedron with edge length are obviously defined by the following equations

ϕx ± y = ±ϕ2
ϕy ± z = ±ϕ2
ϕz ± x = ±ϕ2

or with arbitrary edge length

ϕx ± y = ±3/2
ϕy ± z = ±3/2
ϕz ± x = ±3/2 — Preceding unsigned comment added by StefanDoc (talkcontribs) 13:33, 11 July 2016 (UTC)

Pentakis Dodecahedron net[edit]

Can we get a copy of the CAD file used to make this? My daughter is using it for art and i need to measure the precise angles — Preceding unsigned comment added by (talk) 20:34, 24 July 2016 (UTC)

Complex polytope[edit]

You failed to respond to my edit-comment request to discuss your recent edit on the article talk page, and instead overrode my reversion in clear disregard of WP:BRD. I hope that you will now feel able to read my comments on the talk page and reach consensus before returning to your warring edits. — Cheers, Steelpillow (Talk) 14:33, 4 August 2016 (UTC)

I assumed your objection was to "The body of p{} can be represented by the open region of a real regular p-gon." so I removed that. Feel free to discuss what better fits your understanding. Tom Ruen (talk) 14:37, 4 August 2016 (UTC)
