Group Invariants
Channel: Andrew Misseldine

In this video, we introduce the notion of a group invariant, that is, a property that is preserved by an isomorphism. We demonstrate how to prove two groups are non-isomorphic by invariants. We also discuss some cases when a list of invariants determine the group.
