- Prove statement d of Theorem 3.9: If G is abelian, (xy)n=xnyn for all integers n.True or False Label each of the following statements as either true or false. Let H1,H2 be finite groups of an abelian group G. Then | H1H2 |=| H1 |+| H2 |.In Example 3, the group S(A) is nonabelian where A={ 1,2,3 }. Exhibit a set A such that S(A) is abelian. Example 3. We shall take A={ 1,2,3 } and obtain an explicit example of S(A). In order to define an element f of S(A), we need to specify f(1), f(2), and f(3). There are three possible choices for f(1). Since f is to be bijective, there are two choices for f(2) after f(1) has been designated, and then only once choice for f(3). Hence there are 3!=321 different mappings f in S(A).
