Group actions in abstract algebra

In this first video on group actions, I use an example of some previous work on the symmetric group to give you some intuition about group actions.

Beware when reading your textbook. It is probably unnecessary difficult just due to the dot notation that is used when describing group actions. Group actions are actually a simple concept to understand. In this video I show you how group actions on a set connects the elements in a group with the permutations of a set.

Thank you sir. You explain very clearly.
