 Mersenne prime - Wikipedia, the free encyclopedia
In mathematics, a Mersenne prime is a prime number that is one less than a power of two.
Mersenne primes have a close connection to perfect numbers, which are numbers that are equal to the sum of their proper divisors.
Historically, the study of Mersenne primes was motivated by this connection; in the 4th century BC Euclid demonstrated that if M is a Mersenne prime then M(M+1)/2 is a perfect number.

Pierre de Fermat (August 17, 1601 – January 12, 1665) was a French lawyer and amateur mathematician who is generally given minor credit for the development of modern calculus; in particular, for his work regarding tangents and stationary points.
Fermat worked on number theory while preparing an edition of Diophantus, and the notes and comments thereon contained the numerous theorems of considerable elegance necessary to develop the theory of numbers.
Fermat is famous for his "Enigma" that was an extension of Pythagorean Theorem, also known as Fermat's Last Theorem.

Yves Gallot wrote an excellent Win98/NT4.0/ME/XP program which makes it easy for anyone to find record size or otherwise interesting primes, but this creates a problem: without a coordinated effort, many of us were be searching the same ranges of numbers for primes!
Some spent hundreds of hours checking ranges that were already known to be barren.
