A beautifull day,

i found a probablistic test for Mersenne Prime numbers.
It is not a big deal but i would like to present it to you:

3^(2^p) = 9 mod Mp

It follows directly from the little Fermat.
It is easy and perhaps a little bit faster than the Lucas Lehmer Test.
You need p times squaring and calculating mod Mp

Nice greetings from the primes
Bernhard Helmes
