In addition, the number of open is an example of a rare class of Mersenne primes - these numbers, which take the form of two raised to the power of a prime number minus one. Just a moment of such numbers known 48.
After a new number has been found, it repeatedly tested several other researchers using other computers. The discovery turned out to be true, and as a reward Cooper will receive $ 3,000.
