Let G be a group defined on the set Z with binary relation, +, addition modulo 4, and let G be a group defined on the set Z5 - {[0]} with binary relation, ., multiplication modulo 5. (i) (4 marks) Prove that both, G and G2, are cyclic and write down generators for each group. (ii) (4 marks) For each of the groups G and G2, determine all cyclic subgroups. (iii) (4 marks) Determine whether the groups G and G are isomorphic. Justify your answer.
