The Prime Pages keeps a list of the 5000 largest known primes, plus a few each of certain selected archivable forms and classes. These forms are defined in this collection's home page. This page is about one of those forms. Comments and suggestions requested.

(up) Definitions and Notes

Mersenne primes are primes of the form 2p-1. The first few are 3, 7, 31, 127, 8191, 131071 and 524287 (with exponents p=2, 3, 5, 7, 13, 17, and 19). The Mersennes are also prime for p=31, 61, 89, 107, 127, 521, 607, 1279, 2203, 2281, 3217, 4253, 4423, 9689, 9941, 11213, 19937, 21701, 23209, 44497, 86243, 110503, 132049, 216091, 756839, 859433, 1257787, 1398269, 2976221, 3021377 and 6972593. See our page on Mersenne numbers for more information, history and theorems. Luke's web page on Marin Mersenne is also and excellent starting place.
