| Aug 2, 2021 at 3:32 | comment | added | Semiclassical | I notice the claim of these being regular polytopes. Is there an easy way to verify this? It seems far from obvious (aside from the $(1,1)$ case which is just a simplex), and I find it dubious for even the $(1,2)$ case. (My evidence against: The only convex regular 5-polytopes are the 5-simplex, the 5-cube, and the 5-orthoplex. But these respectively have 6, 32, and 10 vertices, not 8.) | |
