Abstract
Let E be a free product of finite number of cyclic groups, and S a normal subgroup of E such that E/S ≅ G is finite. For a prime p, S = S/S"²Sp = Ì…S/pÌ…S may be regarded as FpG-module. Whenever E is a free group S is called relation module (modulo p) of G; in general S is called relative relation module (modulo p). The aim of this paper is to describe certain relative relation modules of SL(2, p) and PSL(2, p). Here we discuss the cases when S is FpG-faithful.
