A k-subset D of a group G of order v (1 【 k 【 v -1 ) is called a (v, k, )-difference set ifevery nonidentity element of G appears in the list of d1d2-1(d1, d2 D) exactly times. Setn = k - , n is called the order of difference set D.An taomorphism of a finite group G is called a (right) multiplier of
