      Raanan Chermoni continues running my program and has just discovered
      8th known AP24:

      3120744164655323 + 851923*23#*n, for n=0 to 23

      It sets no record (although it has the largest known start).

      Below is list of all known AP24 sorted by progression difference.
      After each progression I have given start and end divided by 10^15:

      1368212299836997 + 148682*23#*n, for n=0 to 23, 1.36821 - 2.13112
      468395662504823 + 205619*23#*n, for n=0 to 23, 0.468396 - 1.52345
      401516288036293 + 608239*23#*n, for n=0 to 23, 0.401516 - 3.52247
