Proof-code: p363

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.)

Persons (*): 1 (counting humans only)

Projects (*): 0 (counting projects only)

Display (HTML): Batalov, OpenPFGW

Number of primes: total 13

Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess'

Score for Primes (*): total 46.8289, on current list 46.6947 (normalized score 7)

Entrance Rank (*): mean 6562.57 (minimum 85, maximum 16774)

Descriptive Data: (report abuse)

This code is primarily used for the potential divisors of double Mersenne numbers (2^M_p-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.
