LARGEST PRIME NUMBER DISCOVERED

Oh, BBC website, how you love your splashy headlines. As any fule no (even those of us who lack a concept of infinity) that there is no largest prime number. But what has been found is the largest Mersenne Prime SO FAR.

What is much more interesting in the story is the name of the project looking for them. The Great Internet Mersenne Prime Search. So therefore GIMPS for short. Ah, how we laughed.
