Sum of all solutions (Posted on 2007-07-20) Difficulty: 2 of 5
Let S(A) be {1,2,3,...,(A-1)} and S'(A,B) be the set of elements X from S(A) that satisfy X^B mod A=1. Assuming that A is prime, find the sum of all the elements of S'(A,B) in terms of A and B.

I observed that right after you posted "Partial Solution"
There is no generalization for this sum for odd GCD values.
But one thing is that sum of all solutions in this case is
divisible by p.

Generally, I submit solutions within a week. You can take
it as granted that I had no solution for a problem if solution
is not posted within that time.
