I’m looking for a complete proof for the following conjecture: Conjecture 1 Mq = 2q − 1 . S0 = 32 + 1/32 , Si+1 = Si2 − 2 (mod Mq ) Mq is a prime iff Sq−1 ≡ S0 (mod Mq ) And we have:
Qq−1 1
Si ≡ 1 (mod Mq ) when Mq is prime
I perfectly know that this test cannot speed up the proof of primality of a Mersenne number. But the method used for proving it could be used to prove that a Mersenne is not prime faster than the classical LLT. Or it could be used for other numbers for which no LLT test does exist. This conjecture makes use of the properties of the cycles of length q − 1 that appear in the Digraph under x2 − 2 modulo a Mersenne prime ; though the LLT makes use of the properties of the tree of the same Digraph. It has been checked with huge values of q. Thanks to the help of H.C. Williams, who suggested me to use the little Fermat theorem, the first part of the conjecture has been proved. Now, how can we prove the converse ?

The first part of the proof makes use of the Lucas Sequence method, as described in many papers and books, like ”The Little Book of Bigger Primes” ´ by Paulo Ribenboim or like ”Edouard Lucas and Primality Testing” by Hugh C. Williams. Here after, (a | b) is the Legendre symbol. All references to theorems apply to properties of Lucas Sequences as given by P. Ribenboim in his book ”The Litlle Book of Bigger Primes” in 2.IV pages 44-etc . Since q is prime, we have: Mq ≡ 1 (mod 6q) . Let: β = 32 and α e ≡ 1/β (mod Mq ) . Since Mq is prime, α e is the only integer such that 0 < α e < Mq . 1
There are an infinity of α > Mq such that α ≡ α e (mod Mq ). Here below, we explain how to compute α e and some α . When q ≡ 1 (mod 3) and since q is odd, we have: q ≡ 1 (mod 6) . Thus Mq = 2q − 1 = 26k+1 = 2(23 )2k − 1 ≡ 1 (mod 9) . Thus 8Mq + 1 ≡ 0 8M +1 (mod 9) = 9e α and α e = 9q ≡ 1/9 (mod Mq ) . When q ≡ 2 (mod 3) and since q is odd, we have: q ≡ 5 (mod 6) . Thus Mq = 2q − 1 = 26k+5 = 32(23 )2k − 1 ≡ 4 (mod 9) . Thus 2Mq + 1 ≡ 0 2M +1 (mod 9) = 9e α and α e = 9q ≡ 1/9 (mod Mq ) . With q > 5, we always have: β < α e
