设G为非交换有限群,|G|=2pq,其中p〈q为奇素数,H为群.不需要群的分类定理,只利用群论初等知识,研究了一类非单群的非交换图和其结构之间的一些联系,得到了若▽(H)≌▽(G),则H≌G的结论.
It has been conjectured that if G and H are two non-abelian finite groups such that ▽(G)≌▽(H),then|G|=|H|and moreover in the case that G is a simple group this implies G≌H.In this paper its aim is to prove that for some groups which are non-abelian group of order 2pq,the graph isomorphism ▽(G)≌▽(H)implies G≌H.
