Los Angeles [UPI] - Computer Scientists using one of the world's
fastest computers believe they have found the largest prime number yet -
one that contains nearly 40,000 digits.
     The Los Angeles Times reported that the prime number was found
using a $9 million Cray XMP computer made by Cray Research in Chippewa
Falls, Wis.
...
     The new prime number, which has yet to be verified, is 2 raised to
the 132,049th power minus 1, a number with 39,751 digits.
...
     Because of its special form, it is called a Mersenne prime, named
for a 17th century monk who investigated them.  If verified, this would
be the 29th Mersenne prime known.  The 28th, which was found last year,
is 2 raised to the 86,243rd power minus 1, a number with 25,292 digits.
