Using these results we prove that A15 is the unique of these groups that is an H*-group, i.e., the groups achieving the upper bound of the order of an automorphism group acting on non-orientable unbordered surfaces.journal articlehttps//doi.org/10.1142/S0218196706002937http://www.worldscinet.com/ijac/16/1601/S0218196706002937.htmlmetadata only access512.7AutomorphismsFuchsian groups and their generalizationsCompact Riemann surfaces and uniformizationKlein surfacesGeometria algebraica1201.01 Geometría Algebraica
