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 L1827, one of those codes.
Code name (*): L1827 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Chatfield, PSieve, Srsieve, NPLB, LLR Number of primes: total 54 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 46.8950, on current list 45.4380 (normalized score 3) Entrance Rank (*): mean 229.67 (minimum 207, maximum 244)
