“…Observe that similar classification results have been obtained for the Suzuki simple groups Sz(q) [11], the groups PSL(3, q) and PGL (3, q) [3], the symmetric groups [8] and the alternating groups [10,9].…”

regular polytopes Thin regular geometries Almost simple groups of PSL(2, q) type Our paper deals with the classification of abstract regular polytopes for almost simple groups with socle PSL(2, q). We consider all almost simple groups PSL(2, q) ≤ G ≤ PΓL(2, q) and determine the maximal rank of string C-group representations for G, i.e. the maximal rank of an abstract regular polytope with automorphism group G, as well as the existence of string C-group representations of lower ranks. Similar results have already been obtained by various authors in the cases G ∼ = PSL(2, q) and G ∼ = PGL(2, q) and they are summarized in this paper.

“…As we pointed out before, Conder and Sjerve and Cherkassoff studied these groups in relation with regular maps. More recently Fernandes and Leemans studied the symmetric groups (see [10]), and then, together with Mixer took care of the alternating groups (see [11] and [12]). …”

For each q ¤ 2 an odd power of 2, we show that the Suzuki simple group S D S z.q/ is the automorphism group of considerably more chiral polyhedra than regular polyhedra. Furthermore, we show that S cannot be the automorphism group of an abstract chiral polytope of rank greater than 4. For each almost simple group G such that S < G Ä Aut.S/, we prove that G is not the automorphism group of an abstract chiral polytope of rank greater than 3, and produce examples of chiral 3-polytopes for each such group G.
