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 L4955, one of those codes.
Code name (*): L4955 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Grosvenor, Srsieve, CRUS, LLR Number of primes: total 14 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 48.3703, on current list 48.3509 (normalized score 48) Entrance Rank (*): mean 1386.85 (minimum 727, maximum 2037)
