I am a graduate student of Mathematics. In our algebra course, I recently learnt group actions.
I want some nice problems on group actions so that I have a firm grasp of the subject after doing those exercises.
I have referred to many books but the problems there are not much interesting. I want some concept-based problems on group actions.
I tried to find it on stackexchange but searching among so many problems is difficult.
So, can someone suggest to me some stackexchange pages or some exercises on group action that will help me to understand the concepts?
