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 p398, one of those codes.
Code name (*): p398 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Stocker, OpenPFGW Number of primes: total 21 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 34.7170, on current list 29.0369 Entrance Rank (*): mean 84782.00 (minimum 84782, maximum 84782)
Below is additional information about this entry.
