Q: Conjecturing when $M$ is good

Sunaina Pati We say an integer $M>1$ is good if whenever $n^n \equiv 1 \mod M$ then we also have $n \equiv 1 \mod M$ and $bad$ otherwise, for any integer $n\ge 2$ . Prove that all odd $M$ are bad. Find all good $M$ . My progress: First taking example, we get Among $M \in \{2,3,4,5\}$ $ , 2,4$ are $good$...

@ArcticChar deleted-tag I agree that the tag with this name could be used inconsistently. The tag linear-system was removed: math.stackexchange.com/posts/3905495/revisions
There is a tag linear-pde for linear PDEs, I did not see a corresponding tag for ODEs. It seems that the combination systems-of-equations+ordinary-differential-equations is often used for systems of ODEs.

@MartinSleziak Well the edit is half-baked and still approved.

I have stayed away from that suggested edit on purpose, since it is a topic I know nothing about.
I have mentioned it here to improve the likelihood that some people with sufficient knowledge might notice the suggested edit.
