Talk:Great disnub dirhombidodecahedron

message: Does anyone else see the summary table (the one that exists for most polytopes on Wikipedia) cover up much of the text, or is that just my computor? Kevin Lamoreau (talk) 04:09, 30 December 2007 (UTC)

replies: text: This is a stub (I think it should be). It fails to explain thoroughly what the great disnub dodo—I can't even pronounce the last part, much less what's so special about this weird spikeball thing is!

text: See uniform polyhedron and Nonconvex_uniform_polyhedron for more examples. This is certainly the most complex one! Tom Ruen (talk) 04:53, 26 July 2009 (UTC)

message: Um...is this a polyhedron? Given that edges coincide, four faces meet at an edge... 4 T C 04:33, 15 February 2010 (UTC)
replies: text: It's all confusing, but it is a topological polyhedron (two faces per edge), and pairs of edges coinciding in geometry. Tom Ruen (talk) 08:53, 3 March 2010 (UTC)

thread_title: Suggestions

message: I would like to see a bit more clarity about how the value of the Euler Characteristic is calculated. From what I understand, chi = F + V - E
The sidebar summary says that this figure has 204 faces, 60 vertices, and 240 edges. So as I do the arithmetic, this gives chi = 24, yet the sidebar says 32.
If the 4-face edges are double-counted, then the article says that the figure would have 360 edges (instead of 240). This change -- according to the article -- makes chi = -88. Yet when I do the arithmetic according to Euler's formula, I get -96. In both cases there is a discrepancy of 8.
I have tried to find other sources that would independently verify these figures, but they all seem to just quote this article.
Is there an error, or am I missing something here? (I admit that I am not an expert in this field!!)Phantor48 (talk) 23:14, 1 March 2016 (UTC)
