      I have over 80 of the remaining values fully factored (for the range
      up to 123(321) I will let some ECM work finish, then post a file
      listing all of these fully factored values, and also post a file
      that contains the "expression form" of the residue of remaining 123
      numbers which contain a composite cofactor. These expressions can
      be fed directly into the current GMPECM 5.1-beta. The expressions
      are like:

      (1234567890*10^143/9999999999)/(3*236701*7797547)

      Which is 123(143) with all known factors listed (3 small ones).

      Jim.
