Abstract

If G is a finite group, X a generating set for G and R some set of relations holding among these generators (but not in general a full set of relations presenting G), we establish sufficient conditions for the group G* = 〈X/R〉 to be infinite and give a lower bound for the rank of the abelianization of the kernel of the natural map G*→G. Related results in the literature and possible directions for generalization are discussed.
