Proof-code: A28

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 A28, one of those codes.

Code name (*): A28

Persons (*): 1 (counting humans only)

Projects (*): 1 (counting projects only)

Display (HTML): Gingrich1, Srsieve, CRUS, PRST

Number of primes: total 7

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

Score for Primes (*): total 50.4516, on current list 50.4516 (normalized score 149)

Entrance Rank (*): mean 1715.86 (minimum 145, maximum 4193)

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

Below is additional information about this entry.

Display (text): Gingrich1, Srsieve, CRUS, PRST

Display (short): Gingrich1

Database id: 10228 (do not use this database id, it is subject to change)

Proof program: PRST The primes from this code accounts for 2.713% of the (active) primes and 0.802% of the (active) score for this program.
