      Here is a new AP13 record at 78 digits:-

      (1374042988+22886141*n)*173#+1 is prime for n=0..12

      All confirmed prime with PFGW -tc

      Input/output statistics:-
      Numbers tested by NewPGen: 2*10^9
      NewPGen reduced these (by sieving to 100G) to: 4.17*10^8
      PRP's found by PFGW: 1.05*10^8
      AP12's found: 21
      AP13's found: 1

      Run-time statistics:-
      NewPGen: 0.3 GHz-days
      PFGW: 2.8 GHz-days
      Pascal program to find AP's: 60 GHz-days

      Poisson was slightly unfavourable: about 15 AP12's should have been
      enough to yield an AP13.

      A new target for you to beat, Jens :-)
