Martin Mačaj:
Enumeration of regular maps on twisted linear fractional groups
Abstract:
We enumerate orientably regular maps of any given type with automorphism group isomorphic to a twisted linear fractional group; these groups form the ‘other’ family in Zassenhaus’ classification of finite sharply 3-transitive groups.
This is a joint work with S. Pavliková and J. Širáň.
