Proposition: Group Homomorphisms with Cyclic Groups

Let \((G,\ast)\) be any group under the operation "\(\ast\)" and let \((\mathbb Z,+)\) be the group of all integers under the operation "\(+\)" (addition). \(G\) is cyclic, if and only if there is a surjective group homomorphism \(f:\mathbb Z\mapsto G\).
