A peaceful and pleasant night for you,
if I know the factorisation or a part of the factorisation of Mp-1
do I have any advantages for checking the primality ?
(Mp should be a Mersenne number)
Or in other words, is the factorisation of p-1 helpful ?
I know the theorem of Pocklington for proofing primality

Thanks in advance if you spend me some lines
Bernhard
