If G is a finite abelian group and n>1 is an integer, we say that G is n-good, if from each factorization of G into direct product of subsets, it follows that at least one of the subsets Ai is periodic, in the sense that there exists such that xAi=Ai. In this paper, we shall study some 3-groups with respect to this property.
