primes! +It has been used in the verification of various Mersenne
primes, +including the 45th, 46th and 48th found Mersenne prime.
+
+You may use it to test any suitable number as you wish,
+but it is preferable that you do so in a coordinated fashion,
+as part of the Great Internet Mersenne Prime Search (GIMPS).
+For more information on GIMPS,
+see <http://www.mersenne.org/prime.html> for details.
