- On p. 204 of Ken Rosen's Elementary Number Theory and its Applications, 2nd ed.
- is a list of the known Mersenne primes, except of course the most recently
- discovered 2^756839-1 (Focus 12:3 (June 1992),3).
-
- (Recall that a perfect even number is of the form 2^(p-1)(2^p-1) where (2^p-1)
- is a Mersenne prime, and that no odd perfect numbers have been discovered.)
