On X-Decomposable Finite Groups for X={1,2,5}
摘要 Let G be a finite group and A ◁ G.Then A is called n-decomposable in G if it is a union of n distinct G-conjugacy classes,and denote n by ncc(A).A group G is called X-decomposable with X={ncc(A)|A ◁ G}.This paper proves that there are only five(isomorphism classes){1,2,5}-decomposable finite groups which are non-perfect.
