It is well known fact that every cyclic group is abelian. But the converse is not true always. i.e. There exists groups that are abelian but not cyclic. Uncountable abelian groups The groups such as and are abelian groups. Since any infinite cyclic group is isomorphic to and hence is countable, the above mentioned groups…
