Why does the soccer ball must have 32 faces? Why not 36 or 40 or any number of face? — Preceding unsigned comment added by 153.20.95.69 ( talk • contribs) 04:05, 8 September 2004 (UTC)
I tried playing around with layout--in IE on my screen there are weird white spaces that I can't seem to correct. (The white spaces were there even before I edited it.) It looks OK in Opera, but even there the football pic winds up all alone under the table. 4.236.78.198 17:32, 21 October 2005 (UTC)
Is there an article on the naming nomenclature of plyhedra or Archimedean solids or whatever? Dalf | Talk 06:45, 2 February 2006 (UTC)
Meaning of the names certainly could/should be described in Archimedean solid. Truncated means you take a polyhedron and slice off the corners, cutting original edges into 1/3rds, so middle third of original edges remain and original faces get doubled - triangles into hexagons in this case. Tom Ruen 07:03, 2 February 2006 (UTC)
Ok I need to add that there's a formula that follows 10E8 which shows that if a fullerene is to the soccer ball as the soccer ball is to the earth.. someone please articulate this and add it thanks!
Given the diameter of a Truncated Icosahedron sphere, how to figure out the side length of associated hexagons and pentagons?-- Jdpan 19:39, 14 February 2007 (UTC)
P.S. You could get the same result from the data provided in the article, that the radius of the circumscribed sphere is sqrt(9φ + 10) (where "φ"=φ = (1+√5)/2) when the edges have length 2. My calculator gives 0.40354821233519770308113433897167 as the ratio... AnonMoos 12:16, 15 February 2007 (UTC)
I think that the "tritium" (or its container) in Spider Man 2 had the shape of a truncated icosahedron... -- Itub 15:16, 13 March 2007 (UTC)
I am trying to build a wire-frame model and I'm looking for the angle of the hex-hex edge compared to the adjoining pentagon face, and the pent-hex edge to the adjoining hexagon face. Are there any good math resources to find these? I would prefer formulas, but angle measurements would be sufficient. -- SDSpivey ( talk) 22:07, 15 December 2008 (UTC)
Are there any sources for this jocular term for this polyhedron? Seems worthy of inclusion.

The current version of the article includes a figure which claims that the chromatic number of the truncated icosahedral graph is 2, but this is wrong, since it is not a bipartite graph. On the other hand, since it is planar, the chromatic number must be no greater than 4. So is it 3 or 4? Noamz ( talk) 20:35, 5 June 2017 (UTC)
sage: g = graphs.BuckyBall() sage: g.chromatic_number() 3
"this shape" seems to refer not only to truncated icosahedrons, but also to to icosahedrons themselves. [And some of the applications are only applications of icosahedrons, and not truncated icosahedrons.] — Preceding unsigned comment added by 65.130.74.174 ( talk) 04:34, 27 August 2019 (UTC)
I believe the origin ball from Pokemon Legends: Arceus is a truncated icosahedron. if someone could verify and add to the article, that would be nice! QuantumChaosTheory ( talk) 20:55, 28 March 2024 (UTC)
I'll bite. Why put two constructions, mostly independent of each other, in one paragraph? It lacks flow. —Tamfang ( talk) 06:08, 11 July 2024 (UTC)
