Congratulations Larry :)

Again from the 2nd drive:
235*2^312345-1 (94028 digits)
133*2^312359-1 (94032 digits)

From the 2nd drive:

167*2^314000-1 (94526 digits)

From choose your own k:

5169615*2^421193-1 (126799 digits)

This was after a gap of about 103000 from the previous prime.

We're closing in on 15k in the top-5000 list now for # of primes
(285 vs. 283) :popcorn:

From the 2nd drive:

From the First Drive
[B]1952775825*2^351809-1 [/B](105915 digits)

From choose your own k:

5169615*2^421525-1 (126899 digits)

Close on the heels of the prime at n=421193. I guess that K was trying
to make up for the large gap between the previous primes. :geek:

Strangely enough I was half expecting to find another fairly quickly, although perhaps not quite that quickly!

From the 2nd drive:
