Here's a prime for an old main-stay very high-weight k that was searched a long time ago at RPS:
2805*2^548291-1 is prime It was previously searched to n=50K and from n=250K-500K. Since we've now filled it with 14 primes on the 12th drive for n=50K-250K, this now makes 92 primes for the k including the above prime. Last fiddled with by gd_barnes on 2010-03-27 at 19:12 |
