CorenBot copyvio question[edit]
The material was split from Packing problem. It was already on wiki, and bears little similarity to the single sentence definition given on this link. I don't think there is any copyvio problem here (and I certainly never used that site as a source). --99of9 (talk) 05:01, 1 June 2011 (UTC)
Add a section on proof methods?[edit]
If "Circle packing in a circle" deserves its own page, one should attempt to list some known proof methods too (cf. similar discussion entry in Talk:Packing_problem).

"Trivially optimal"[edit]
Are the 5- and 6- circle cases really "trivially optimal"? Especially with the 6-circle case, I picture a 3x2 rectangular array, or perhaps staggered, as options... they might be pretty clearly bad options, but if I have to think about it, it's not trivial. And how can the 5-circle case be both proved by someone in 1968 and also be trivial? I mean sure, it looks trivial, but by that standard people could argue that for the 19-circle case or whatever.

"density" values[edit]
At least two density values are slightly too high; I'll edit that. The two in question are cases 6 and 7, where 6/9 and 7/9 are given as 0.6667... and 0.7778... respectively. Both are a bit too high. Although they round to the decimals stated, that rounding is up in both cases; the decimal fractions do not actually start with 0.6667... or 0.7778. 84.140.35.194 (talk) 13:07, 5 March 2019 (UTC)
Algebraic numbers[edit]
Should radii involving polynomial roots without closed form have their equations given? For example, the radius r of the smallest circle enclosing 12 packed circles being the root of 27r^10-270r^9+891r^8-648r^7-2826r^6+7884r^5-8050r^4+2104r^3+11151r^2-19310r-169 near 4. 76.121.231.9 (talk) 18:57, 21 April 2024 (UTC)
