THEOREM 1. Let G be a nonabelian simple group with H< G and [G: H]= pa, p prime. One of the following holds.(a) G= A, and HrA,-, with n= p’,(b) G= PSL,(q) and H is the stabilizer of a line or hyperplane. Then [G: H]=(q”-l)/(q-1)= p”.(Note n must be prime.)(c) G= PSL,(ll) and H? A,.(d) G= M,, and H% Mzz or G= M,, and HrM,,.(e) G= PSU,(2) z PSp,(3) and H is the parabolic subgroup of index 27.
