Answers to questions about medial layer graphs of self-dual regular and chiral polytopes

Marston Conder, Isabelle Steinmann

An abstract $n$ -polytope $P$ is a partially-ordered set which captures important properties of a geometric polytope, for any dimension $n$ . For even $n \geq 2$ , the incide…
