I've been known to give RDS perhaps more leeway than he deserved, but can we please this troll already

As long as their activities are confined to specific sub-fora and/or specific threads, I am happy to leave them be. We're not obliged to spend time on them in anyway. Ignore list is probably the best option in context.

There is no known proof that there are an infinity of Mersenne primes.

Also the gap between M37 and M38 exponents is greater than "1.5"

Sorry for not complying with...

The Few exponents I am referring to are 13, 107, 127, 1279, 11213, 110503, 132049, 1257787, 1398269, 13466917.......

The pattern probably continues for 9 digits as well, so there is probably a mersenne prime between 2^99999999 and 2^149999999

M71324207525210468041 has 0 factors in [2^1, 2^105-1].
Anybody cares to go further?

Trial factoring may not be the best idea here.

well we know LL will likely take longer etc. at some point at which case a primality ( typically done with the LL test for Mersennes) or factoring algorithm of some sort may be the way to find it composite.

right... There is also the N+1 primality test to apply.
