Open the number refers to the so-called "Mersenne prime", which have the form 2p - 1, where p - a prime number. For the new number p = 43112609, and in himself, to be precise, 12978189 marks.

Significantly, this is the eighth Mersenne prime discovered in the heart of distributed computing, University of California Los Angeles. The project was supported by GIMPS (Great Internet Mersenne Prime Search), an organization that brings together over the Internet computers around the world to perform calculations needed for the search and verification of Mersenne primes.

For his discovery, project participants will receive the award - a $ 100 thousand dollars assigned for the detection of Mersenne numbers with the uniqueness of over ten million, according to the channel «Fox News».
