(2,m,n)-groups with Euler characteristic equal to -2^as^b

Group Theory 2012-05-24 v1 Combinatorics

Abstract

We study those (2,m,n)(2,m,n)-groups which are almost simple and for which the absolute value of the Euler characteristic is a product of two prime powers. All such groups which are not isomorphic to PSL2(q)PSL_2(q) or PGL2(q)PGL_2(q) are completely classified.
