  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 g187, one of those codes.

Code name (*):g187   (See the descriptive data below.)
Persons (*):1 (counting humans only)

The searches and proofs for primes such as 2*994871^13005+1 Divides Phi(994871^13005,2) were performed using OpenPFGW.  Proth.exe is credited merely for the proof of divisibility.
