                                   1.  Compute all possible finite abelian groups of order n. What is the largest n for which it
                                       will work?
                                   2.  Find all finite abelian group of order less than or equal to 40 up to isomorphism.
                                   3.  Find all finite abelian groups of order 200 to 720 up to isomorphism.

                                   4.  Show that the infinite direct product G = Z  × Z  × . . . is not finitely generated.
                                                                              2

                                   5.  Let G be a finite abelian group of order m. If n divides m, prove that G has a subgroup of
                                       order n.
