2975*2^478798-1 is prime

With this prime, that now makes 61 total primes for n=460K-480K for the 11th drive vs. 60 total primes for n=440K-460K. After a long n=1300 dormant stretch for n=476K-477.3K (new primes dormant for n=1800 from 475.6K-477.4K!), that now makes 10 primes in an n=1500 stretch from 477.3K-478.8K. 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. :smile:

The remarkable prime range for the 11th drive continues:

2581*2^479071-1 is prime
2335*2^479093-1 is prime


That now makes 12 primes in an n=1800 stretch from n=477.3K-479.1K. :smile:
