GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) Ramanujan primes are the integers R_{n} that are the smallest to satisfy the condition (x)  (x/2) > n, for all x > R_{n}. In other words, there are at least n primes between x/2 and x, whenever x is greater than or equal to R_{n}. The sequence begins 2, 11, 17, 29, 41, ....
