Proof-code: p297

Previous Next Random

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 p297, one of those codes.

Code name (*): p297 (See the descriptive data below.)

Persons (*): 1 (counting humans only)

Projects (*): 0 (counting projects only)

Display (HTML): Broadhurst, Srsieve, NewPGen, LLR, OpenPFGW

Number of primes: total 16

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

Score for Primes (*): total 46.4505, on current list 45.1107 (normalized score 1)

Entrance Rank (*): mean 88.00 (minimum 88, maximum 88)

Descriptive Data: (report abuse)

In this code, I acknowledge my debt to Paul Jobling's NewPGen and to Geoffrey Reynolds' srsieve, for different stages of sieving, and then to Jean Penne's LLR and to OpenPFGW, for alternative modes of hunting for probable primes. So far, 16 near-repdigit primes were found and proven by Version 3.4.3 of OpenPFGW, yet each of the 4 cited programmes played an important role in the overall process.

I am a member of this code and I would like to:
