I don’t mean to sound stupid. But I got a formula to work out the remainder for mod Mersenne Prime, working backwards on the Lucas Lehmer Primality Test Sequence. The sequence is (s^2) - 2 moving forwards. Is this publishable? If so, where? It seems really obvious to me but I can’t see anything on Wikipedia. And on Wikipedia they’ve put that some guy proved one step going backwards on the sequence = +/- 2^((p+1)/2) but no mention of ANY step????
