Non-flat regular polytopes and restrictions on chiral polytopes

Combinatorics 2017-06-06 v1

Abstract

An abstract polytope is \emph{flat} if every facet is incident on every vertex. In this paper, we prove that no chiral polytope has flat finite regular facets and finite regular vertex-figures. We then determine the three smallest non-flat regular polytopes in each rank, and use this to show that for n8n \geq 8, a chiral nn-polytope has at least 48(n2)(n2)!48(n-2)(n-2)! flags.
