      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
