Abstract:Abstract. We prove that every finite non-abelian simple group acts as the automorphism group of a chiral polyhedron, apart from the groups P SL2(q), P SL3(q), P SU3(q) and A7.
“…and PSU 3 (q) to the list of exceptional groups. More specifically, by Theorem 1.4, [8, Theorem [15,Theorem 1.1], and some known results on alternating groups [11] and classical groups [24], we obtain the following result.…”

“…For G = PSL 4 (2) ∼ = A 8 , (2.4) may fail. However, we can see from[8, Theorem 1.3] and[15, Section 5] that G has a cubic GRR with connection set {z, z −1 , y}, where y is an involution and |z| = 7, though 7 / ∈ ppd(2, 4).…”
A recent conjecture of the author and Teng Fang states that there are only finitely many finite simple groups with no cubic graphical regular representation. In this paper, we make crucial progress towards this conjecture by giving an affirmative answer for groups of Lie type of large rank.

“…In [16] Leemans and Liebeck proved these results in one direction, showing that all non-abelian finite simple groups except those in L have such a generating pair x, y, and are therefore automorphism groups of orientably regular chiral maps, that is, members of G(2 P ex). For the converse, it is easy to show that L 2 (q) and A 7 have no such generating pairs, and in [2] d'Azevedo Breda and Catalano proved this for the groups L 3 (q) and U 3 (q), thus completing the proof of Theorem 1.3.…”
Building on earlier results for regular maps and for orientably regular chiral maps, we classify the non-abelian finite simple groups arising as automorphism groups of maps in each of the 14 Graver-Watkins classes of edge-transitive maps.
