Ok,

  I've come up with this SWAHBI (like a SWAG, but an idea
instead of a guess).

  What I'm looking for is the following two items for *all*
Mersenne numbers 2^p-1 where p is prime and p>1:
  1) All known factors (including, but not limited to,
     the smallest known factor (noted if it isn't))
  2) Largest potential factor attempted
  I ask that the two items are human-readable at the
very least.

  I've pulled a couple of files off mersenne.org 
(FACTORS.ZIP and NOFACTOR.ZIP) as well as off 
Alex Kruppa's page.  While the files appear complete
as far as I can tell, they only cover the ranges
of p between 11 - 9,999,991 and 33,219,281 - 35,999,993.
They also don't cover *all* known factors!
  Any and all information on the ranges between
10M - 33.22M and >36M is greatly appreciated, as well
as any known factors not listed in the files I've
pulled.

Eric Hahn
