Some Topics on n-decomposable Groups

Let G be a finite group and Jet NG denote the set of all non- trivial proper subgroups of G. A member K of No is called n-decomposable if K is the union of n distinct conjugacy classes ofG. The group G is called n-decomposable if NG (not equal to) and every member of NG is n- decomposable. In this paper we investigate the structure of n-decomposable finite groups for n<6 and classify them in the class of finite non-perfect groups.
