    Here is a new AP7 record at 1328 digits:- (1246733996+35777939*n)*3109#+1 is prime for n=0..6 All confirmed prime with PFGW -tc Input/output statistics:-

      Here is a new AP7 record at 1328 digits:-

      (1246733996+35777939*n)*3109#+1 is prime for n=0..6

      All confirmed prime with PFGW -tc

      Input/output statistics:-
      Numbers tested by NewPGen: 1*10^9
      NewPGen reduced these (by sieving to 4 trillion) to: 2.78*10^8
      PRP's found by PFGW: 2,067,593
      AP6's found: 204
      AP7's found: 0
      The AP6's were all extended upwards and 1 AP7 found.
      The search program was terminated at this point, about half way through.

      Run-time statistics:-
      NewPGen: 19 GHz-days
      PFGW: 204 GHz-days
      Pascal program to find AP7: 10 GHz-hrs

      The expected AP6 count to get one AP7 was about 300.

        Congrats! But this will not register as a record
        at the Prime Pages until PrimeMogul manually
        corrects your syntax (7 times over).

        You submitted the comment

        forgetting the canonical format, exemplified in

        More work for Chris's fingers...

            I didn't want to make more work.
            It's such a big site I find it hard to find the right format.
            What I typed was my 3rd attempt at getting it accepted.
            Perhaps a "Help" comment on the submission page to refer to the "Official Comment" entry on a similar prime, like this one:
            http://primes.utm.edu/primes/page.php?id=91154
            would make it less likely for CC having to edit people's submissions?

            Anyway, sorry, Chris.

              Hi Mike
              Just noticed this.
              congratulations.
              Looks like your AP10 record is safe.
              I've been looking at n*653#
              Found all primes between n=1e9 and 2.5e9 and extended all aps from 6 and up.
              No luck yet with only about 10% left to test

              cheers
              Ken
