The mapping from Zn to Z by a rightarrow a is a group homomorphism. If beta is an odd permutation, then beta -1 is odd. If G is a finite group and m divides the order of G, then there exists a subgroup H of G of order m. In a group of prime order, any subgroup is normal. If K is a normal subgroup of a group G and H is subgroup of G, then K H is a normal subgroup of H.
