    Gary, ... I have just sieved up to 10^14 with nothing being found. The best was 45077834116589, which generated 18 primes for x in [0..29]. The runtime was 395

      I have just sieved up to 10^14 with nothing being found. The best was
      45077834116589, which generated 18 primes for x in [0..29]. The runtime was
      395 seconds on this 450 MHz PIII.

      Regards,

      Paul.
