Abstract

A maniplex of rank nn is a combinatorial object that generalises the notion of a rank nn abstract polytope. A maniplex with the highest possible degree of symmetry is called reflexible. In this paper we prove that there is a rank 44 reflexible maniplex with automorphism group PSL2(q)\textrm{PSL}_2(q) for infinitely many prime powers qq, and that no reflexible maniplex of rank n>4n > 4 exists that has PSL2(q)\textrm{PSL}_2(q) as its full automorphism group.
