Mathematicians May Win $100,000 Prize for Prime Number Discovery

Mathematicians at UCLA believe they have found a very long and very special prime number: It clocks in at nearly 13 million digits, and belongs to an elite group of numbers called Mersenne primes. If the math checks out, the discovery will win UCLA's math department a $100,000 prize that was offered for the first Mersenne prime found with over 10 million digits.
