I have a question about primitive roots. I'm just trying to come up with general strategies that would help we remember tricks on how to find all primitive roots. So I came up with a few basic cases and perhaps one of you could explain how to solve them. Here it goes:
Find all primitive roots for:
ii) 2 * 13
iv) 2 * 13^4
Thanks again for your help. I appreciate it. Happy Easter.
There's no good way to find primitive roots. There is one computer algorithm which runs in polynomial time *under GRH*, so really I believe that there's no general way to do it.
However, 2 or 3 usually works. Check these two before you complain about finding primitive roots.
