  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 CD, one of those codes.

Code name (*):CD   (See the descriptive data below.)
Persons (*):2 (counting humans only)
Projects (*):0 (counting projects only)
Display (HTML):Caldwell, Dubner, Cruncher
Number of primes:total 31
Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess')
Score for Primes (*):total 32.2999, on current list 32.0237
Entrance Rank (*):mean 465.40 (minimum 79, maximum 1304)

Proofs were done with the Dubner Cruncher hardware and code that both Harvey Dubner and I wrote for it.
