Proof-code: p405

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 p405, one of those codes.

Code name (*): p405

Persons (*): 1 (counting humans only)

Projects (*): 0 (counting projects only)

Display (HTML): Propper, Cksieve, OpenPFGW

Number of primes: total 10

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

Score for Primes (*): total 51.4513, on current list 51.4483 (normalized score 397)

Entrance Rank (*): mean 1283.88 (minimum 48, maximum 2735)

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

Below is additional information about this entry.
