      For over a week I have been using 40-60 64-bit computers in an attempt
      to find 2 AP22 with common difference. I have selected 43# as the
      common difference. While the first AP22 was found early in the search,
      the second one appeared today. It also improves the current AP22 record.

      Known AP20+ with difference 43#
      First terms of progressions are given
