Abstract: Let G be a group of order 4p4, N be a normal subgroup of G and D be a hypothetical Menon difference set in G, by investigating the intersection numbers, some necessary conditions are gotten.

Key words: difference sets, intersection numbers, complete cyclic basis

摘要: G是4p4阶群,NG的一个正规子群,假设DG中的一个差集,通过考察相交数,得到一些D存在的必要条件。
