Talk:2 31 polytope

Coordinates
What are the vertex coordinates of this polytope? Are they essentially the same as those of E7? --Marozols (talk) 22:13, 13 August 2010 (UTC)

I haven't computed them. They can be seen as the center of the orthoplex facets of the 3_21_polytope polytope whose coordinates are listed in 8-space. It requires a brute search, but not too huge maybe. I'll update if I do it! Tom Ruen (talk) 19:37, 14 August 2010 (UTC)
