GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) The sum of the first 8888 primes is 386848087. Note the four 8's. [Blanchette] 8888 can be expressed as the sum of two consecutive primes (4441 + 4447). [De Geest] 8^{1} + 8^{0} + 8^{3} + 8^{3} = 1033, the concatenated exponents. [De Geest] The only fourdigit repdigit such that the product of itself and all truncations of itself plus one is prime, i.e., 8888*888*88*8 + 1 is prime. [Opao] The only fourdigit repdigit such that the sum of itself and all truncations of itself minus one, i.e., 8888+888+88+8  1 = 9871 is an emirp. [Bajpai]
