English term or phrase:bounds of a long
To test for a Mersenne prime, our service will apply the Lucas-Lehmer test using Java's BigInteger class. We must use the BigInteger class to search for new Mersenne primes, because current Mersenne primes significantly exceed the bounds of a long.
A Mersenne (also spelled Marsenne) prime is a specific type of prime number. It must be reducible to the form 2n - 1, where n is a prime number. The term comes from the surname of a French monk who first defined it. The first few known values of n that produce Mersenne primes are where n = 2, n = 3, n = 5, n = 7, n = 13, n = 17, n = 19, n = 31, n = 61, and n = 89.
