Such a group is also isomorphic to Z/nZ, the group of integers modulo n with the addition operation, which is the standard cyclic group in additive notation. Under the isomorphism χ defined by χ(g i) = i the identity element e corresponds to 0, products correspond to sums, and powers correspond to multiples. 1.Find an isomorphism from the group of integers under addition to the group of even integers under addition. Let 2Z be the set of all even integers. Deﬁne a map ˚: Z !2Z as ˚(n) = 2n. We claim that ˚is an isomorphism. ˚(n) = ˚(m) )2n= 2m)n= mso it is onetoone. For any even integer 2k, ˚(k) = 2kthus it is onto. Also The symmetric group S n S_n S n is also nonabelian for n ≥ 3 n \geq 3 n ≥ 3. Rings are also examples of abelian groups, with respect to their additive operations. Further, the units of a ring form an abelian group with respect to its multiplicative operation.
