    Phil Carmody and I have found the record generalized BiTwins with one link: 570323880*(16500#/673949)*8087388^n +/- 1, for n = 1,2 (7120,7127 digits)

      Phil Carmody and I have found the record generalized BiTwins with one link:

      570323880*(16500#/673949)*8087388^n +/- 1, for n = 1,2 (7120,7127 digits)

      1368777312*(16500#/923935)*4619675^n +/- 1, for n = 1,2 (7120,7127 digits)

      The 7120-digit twin is actually the same in both cases:
      6843886560*16500# +/- 1

      PrimeForm/GW prp'ed and proved the primes after the "TreeSieve" algorithm had
      sieved candidates to 5*10^11.

      Henri Lifchitz keeps the records at
      http://ourworld.compuserve.com/homepages/hlifchitz/Henri/fr-us/BiTwinRec.htm

      September is the 5th month in a row this record is improved.
      The last 4 were by different people. Anybody in October?
