Just a quick explanation of what I have done here. The headings for 22 to 29 is so that the actual number pages can have redirects to a defined point in this page. — Preceding unsigned comment added by AndrewKepert (talkcontribs) 06:36, 10 November 2003

The only problem with this, AndrewKepert, is that such a redirect doesn't actually work: the URL used by the browser is not changed by the redirect, and so contains no "#..." element. In other words, it still only points to the top, which is rather confusing if you follow a link to, say, twenty-nine. Perhaps it would be better to also have a heading for twenty itself, below a line explaining which numbers this page (currently) covers. This would make it clearer why the user had been redirected; it would also add an entry for twenty itself in the table of contents [if enabled], and move this into clearer view. (it frequently annoys me that these contents boxes don't appear until the first explicit heading, which can be a long way down the page) Obviously, this policy would then have to be applied to the other number articles that are in this form.

I changed the formatting a bit, maybe it's easier to read now. Feel free to modify it.
BTW I was wondering why Special:Whatlinkshere/Twenty didn't show all the twenty-... redirects. Must be the anchors.

Certainly makes it clearer what's covered if you have the TOC turned on. I'm not sure whether placing the other numbers at a lower level of hierarchy makes sense, though, and it needs a proper introduction at the very top. I was holding back from fiddling until a consistent design had been agreed on, as it will also need to be applied at similar pages such as Thirty, Hundred and so forth. In fact, perhaps we need a Wikipedia:WikiProject Numbers template, since the layout of the information on each number is also somewhat variable at present... - IMSoP 23:14, 7 Dec 2003 (UTC)

Yes I know that it only half-worked -- it was a bit of an experiment that I left in place to draw attention to a problem that could either be fixed by a more creative solution in the current wiki engine, or by tweaking the wiki engine to handle in the obvious way. My workaround solution (aka kludge) to fix the other half was to create links like Twenty-eight#Twenty-eight or more probably Twenty-eight which currently work and degrade gracefully once a page for twenty-eight is created. I think the page in its current form is good. However, since I did the big rearrangement it has attracted interest and the sections have grown to the point where they could be split off. (This was partly my fault for raising "thirty-eight" as being "the first boring number" ... another story.) -- AndrewKepert 02:05, 9 Dec 2003 (UTC)

In the meantime (before reading above explanation), I had fixed the remaining redirects. I had preferred to see Whatlinkshere working. I suppose the anchor part still works.
Indeed, it would be nice to have a template. To some extent I followed fourteen. I spent some time building links from the year pages, even if the current format could probably also be improved. BTW 20 would be the part of twenty (currently 20-29) to spin-off, but the current pape is still of readable size. -- User:Docu — Preceding unsigned comment added by Docu (talkcontribs) 06:44, 9 December 2003


Under mathematics, this article says "21 is the total number of digits on the human body". The disambiguation page for Digit says digits can be fingers and toes. Shouldn't this article say there are 20 digits on the human body? — Preceding unsigned comment added by (talk) 01:42, 24 July 2006‎

Age 20[edit]

Deleted this section. The statement that one is officially an adult at age 20 is incorrect in many, if not most jurisdictions. The term adult in an legal contexct may have several meanings, but more common ages of majority are 18 or 21. —Preceding unsigned comment added by Cmsg (talkcontribs) 16:45, 27 November 2007 (UTC)

20 in sports[edit]

Do we really the sports stars who wear the number 20? Where does it stop? They should either all be removed, or at least trimmed to only the particularly noteworthy personalities. Psym (talk) 02:22, 20 October 2009 (UTC)

Verification Requested[edit]

When Lincoln said in the Gettysburg Address "four score" (meaning 20 years), it suddenly clicked to me that four scores, as in the old roman counting system where each four vertical slashes with a horizontal slash thru the four (a score?) was a count of five. Is that a correct interpretation of a score? -- (talk) 01:18, 19 November 2011 (UTC)

In currency[edit]

I've deleted this section. It had mentioned the UK ₤20 and US $20 bills and whose portrait was on them. Why only these two. How about euros, NZ dollars, Canadian dollars, etc.? How about coins 20¢, 20p, etc.? It might be interesting, though, to note that 20 is a common denomination for currencies in general (though no Canadian or US 20¢ pieces exist) and that there used to be 20 shillings to the pound.

No disambiguation page?[edit]

I had removed the Music section which, rather than dealing with the number twenty (the topic of this page), was a list of musical things with "twenty" or "20" in their names. It seemed to me that this kind of thing belongs at a disambiguation page. That's what we usually do with off-topic stuff with a related name. M0rphzone, however, reverted this stating "there is no other disambiguation page; this is it; see talk and the other number articles". Well, there is a disambiguation page but if there weren't, there should be. As for the other number articles, there are disambiguation pages for many of them too. Even if these disambiguation pages didn't exist, it wouldn't follow that they shouldn't. Disambiguation belongs on disambiguation pages. These number pages should be about numbers. Anyway, I came to talk as M0rphzone suggested and there was nothing here to justify his reverting me. JIMp talk·cont 09:35, 3 February 2013 (UTC)

Really. You think I would just revert without checking? The fact that it was so hard to find—maybe that tells you something? If there is a dabpage, then why is it not linked in the dab? Why does the dablink redirect here? Why did you not properly update the links after moving the page? There're only 4 links that link to 20 (disambiguation). Next time fix them and clean up after your edits. Do you expect people to clean up after you? - M0rphzone (talk) 06:06, 4 February 2013 (UTC)
Of course I don't expect people to clean up after me. If I missed something, I'm sorry. I'm also sorry for assuming that 20 (disambiguation) would be easy to find. JIMp talk·cont 01:37, 5 February 2013 (UTC)

"It appears that"[edit]

The claim that <quote>20 is the only number with more than one digit that can be written from base 2 to base 20 using only the digits 0 to 9</quote> is sourced to a website where this assertion is moderated by an <quote>"It appears that"</quote>. Shouldn't we do same here? elpincha (talk) 17:08, 11 March 2013 (UTC)

Number 20 in percent encoding / URL encoding[edit]

I want to add this

*In [[Percent-encoding#Character_data|percent-encoding]], %20 represents the punctuatcion [[Space (punctuation)|space]] in URL encoding

under the "In science" section. Another user disagrees and argues that is it not helpful and that the addition is not related to the "number 20". I argued that there are a couple of entries in this article that is not the "number 20" in a strict sense, but add value to the article none the less and that linking to percent encoding may help some readers find what they are looking for. Does anyone else want to give input? --Bensin (talk) 15:24, 30 March 2014 (UTC)

It is really not a twenty, it is a two-zero. Even though I know this, it is percent-twenty to me when I see it. To me it should be in the article but perhaps create a new heading section for "Things that look like 20 but aren't"--☾Loriendrew☽ (talk) 18:07, 30 March 2014 (UTC)

Retired jersey numbers[edit]

Per WP:PRESERVE, here is the list of retired #20 jersey numbers and racecars that were mentioned in the article:
