WebThis exercise describes 13 isomorphism types of groups of order 56. (a) Prove that there are 3 abelian groups of order 56. Solution: From HW 2, Problem 2, we know that every finite abelian group has a unique de- composition as the product of cyclic groups in invariant factor form.

Let's apply this to find ( 1, 1) . ( 1, 1) + ( 1, 1) = ( 2, 2)

A cyclic group is a group which is equal to one of its cyclic subgroups: G = g for some element g, called a generator of G . For a finite cyclic group G of order n we have G = {e, g, g2, ... , gn−1}, where e is the identity element and gi = gj whenever i ≡ j ( mod n ); in particular gn = g0 = e, and g−1 = gn−1.
