  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 p162, one of those codes.

Code name (*):p162   (See the descriptive data below.)

By combining primes on Chris Caldwell's list, David Broadhurst used PFGW to find a third prime that forms an arithmetic progression with smaller primes found by Peter Grobstich and Mark Anderson. All three are credited, since the largest prime would be of little interest without the other two. It is pleasant to record that the two seeds came from Wilfrid Keller's accurate compilation of primes of the form k*2^n-1 with odd k < 300. David thanks Chris and Wilfrid for their high standards of record keeping and collegiality.
