I know how to do it with smaller numbers by testing,but here we have φ(φ(41))=16 solutions out of 40 possibilities.I think I somehow have to use indices. Actually how do I even find 1 primitive root?Should I just pick a random number and test? Any help will be appreciated.

How can I find all primitive roots of 41?
