  Samuel Yates began, and this site continues, a database of the largest known primes. Primes in that database are assigned a proof-code to show who should be credited with the discovery as well as what programs and projects they used. (Discoverers have one prover-entry, but may have many proof-codes because they use a variety of programs...) This page provides data on p363, one of those codes.

Code name (*):p363   (See the descriptive data below.)

Descriptive Data: (report abuse)
This code is primarily used for the potential divisors of double Mersenne numbers (2Mp-1). PFGW is used to prove primality (with the respective Mersenne prime as a helper prime). The candidates are sieved with a custom program, and then tested for primality and finally for double Mersenne number divisibility.
