4223272*3^134986-1 is prime.

This means only 1 k to go

Now a quick question, for Gary:

The primes for Riesel base 3 for k<=500M for n<=500 are you interested in having those or will you rediscover those primes again, once you continue constructing or others continue constructing the proof for Riesel base 3 conjecture?

KEP!
