2975*2^4787981 is prime
With this prime, that now makes 61 total primes for n=460K480K for the 11th drive vs. 60 total primes for n=440K460K. After a long n=1300 dormant stretch for n=476K477.3K (new primes dormant for n=1800 from 475.6K477.4K!), that now makes 10 primes in an n=1500 stretch from 477.3K478.8K. A remarkable run of primes to give the higher 20K range more primes than the lower one. The primes are doing their normal "strange" thing. Last fiddled with by gd_barnes on 20090904 at 04:50
