        It's extra special in that it's the first ECM record which is smaller than the previous ECM record (at 79 digits, http://www.loria.fr/~zimmerma/records/top50.html )!

          They just wanted a record that had a non-prime number of digits...
          having a prime number of digits is a different world record!
