Isomorphism of Groups is an equivalence relation - Chapter 9 - Lecture 2

In this video we prove that isomorphism is an equivalence relation on the collection of all groups. We begin by proving that every group is isomorphic to itself. For this we prove that the identity function from a group G to itself is an isomorphism. Hence isomorphism is a reflexive relation. We then prove that this relation is also symmetric as well as transitive.
