Proof-code: x28

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 x28, one of those codes.

Code name (*):x28   (See the descriptive data below.)
Persons (*):1 (counting humans only)
Projects (*):0 (counting projects only)
Display (HTML):Iskra
Number of primes:total 22

Score for Primes (*):total 44.3565, on current list 42.9211
Entrance Rank (*):mean 108.00 (minimum 108, maximum 108)

Descriptive Data: (report abuse)
Proving primality using a test for numbers of the form A23n+1, n odd, described in a paper published by me and Pedro Berrizbeitia in the Proceedings of the American Mathematical Society 130 (2002), 363-365.

I have several computers in the mathematics department running a program written in C testing these numbers.

I am a member of this code and I would like to:
Edit the descriptive data above as:
