 2014-12-04, 14:03 #187 unconnected     May 2009 Russia, Moscow 32·281 Posts BTW, there was a gap between NPLB(n<600k) and RPS 11th drive (started from n=666666). I checked this range for k=2001-2049 and found some primes: 2007*2^619422-1 2009*2^640696-1 2007*2^658365-1 2009*2^660920-1 2045*2^662044-1 2013*2^660179-1 2019*2^661337-1 2037*2^628032-1 2037*2^638768-1
