SUBORBITAL GRAPHS FOR THE NORMALIZER OF\Gamma_o(N)

Authors: M. AKBAŞ, T. BAŞKAN

Abstract: In this paper we examine some properties of suborbital graphs for the normalizer {\cal N} of \Gamma_{0}(N) in PSL(2,R) and show that, if {\cal N}/\Gamma_{0}(N) and the set of orbit representatives are denoted by B and \Omega respectively, the permutation group (B,\Omega) is regular and m-regular where m is an odd natural number.
