Pyramids Over Regular 3-Tori
Daniel Pellicer, Gordon Williams · SIAM Journal on Discrete Mathematics · 2018
In this paper we exhibit the first infinite family of abstract 4-polytopes whose connection groups are not string C-groups. In addition we present some new results on methods of representing the connection group of a polytope in terms of its automorphism group. We also analyze the connection groups of all of the pyramids over the finite regular 3-tori.
