Let D be a (v, k, \*)-difference set in a group G. Assume that G has a normal subgroup N such that GรN is cyclic or nearly cyclic. Under the self-conjugacy assumption on exp(GรN), we shall give bounds on |N| and \*. The theorem is applicable to a wider variety of parameters for groups, not necessari
