More importantly do these n, follow log2(log2(Mn)) ?
I believe Mersenne primes will always have the largest exponent n up
to that point. I wonder if all "largest" n, include the sequence of
primes p?
It takes about a half hour with proth.exe to list all Riesels less
than 2^31. But sorting them is another story...

If there is some property or critera(*which it seems there is) to
follow this line of n, It would make for a great sister search for
mersenne/like primes. To fill in the general gaps with the local
distinction.
*Each one is related to the next
