      The discovery was made by a member of BOINC@Poland team, who would
      like to stay anonymous.

      A few members of BOINC@Poland team are conducting a limited
      distributed search, splitting the search ranges by hand. I have
      furnished them with the searching program, but I am not taking part in
      the search myself.

          Note that the previous smallest known start was 275955343.
          It is pure coincidence that the new record is almost the same.

                  Congrats.
                  http://users.cybercity.dk/~dsl522332/math/aprecords.htm is updated.
                  I have added tables with record histories for the smallest known difference,
                  start and end in an AP-k, going back to January 2005 when the page opened.
