I mean you can find three random numbers (a, b, c) that respect that :

a+b+c = 2^n-1
and a²+b²+c²=(4^n-1)/3

If a+b+c is a prime Mersenne number.

you can't find any numbers for example for...

Hi and thanks for your reply.

And by the way I noticed something interesting : if a+b+c = 2^n-1 you can found number with a²+b²+c² = (4^n-1)/3 and it seems it works with Mersenne number (it seems...

Hi

I would like to know if a^(2^n) mod (2^n-1) = a² when a is between 0 and sqrt(2^n-1) and a is an integer when 2^n-1 is prime and only if it's prime ?

I tried this with some Mersenne...
