    Here is a new AP7 record at 1402 digits:- (280120647+30017636*n)*3301#+1 is prime for n=0..6 All confirmed prime with PFGW -tc Input/output statistics:-

      Here is a new AP7 record at 1402 digits:-

      (280120647+30017636*n)*3301#+1 is prime for n=0..6
      All confirmed prime with PFGW -tc

      Input/output statistics:-
      Numbers tested by NewPGen: 2*10^9
      NewPGen reduced these (by sieving to 5 trillion) to: 5.3*10^8
      PRPs: 1,769,982
      AP5s: 34,990
      AP6s: 129
      AP7s: 1

      Run-time statistics:-
      NewPGen: 27 GHz-days
      PFGW: 206 GHz-days
      Pascal program to find AP7: 7 GHz-hrs

      When the AP7 was found the PFGW run was terminated, about 20% of the way through.
