Finite Direct Products,groups to modules over a principal ideal domain, we show that this result gives canonical forms for matrices. The essential uniqueness of the factorization of a finite abelian group as a direct product of cyclic .-groups is then generalized to nonabelian groups that arc direct products of “indecomposable” groups.
