GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) In the race for most appearances by a digit in the first n primes, the four prime digits (2,3,5,7) tie for an early lead but soon lose it to 1 which stays in the lead or tied for the lead until, ironically, the 1111th prime (8933) at which point the digit 3 pulls ahead 623 to 621. [Gaydos] The least prime p that is a substring of (p1) * p * (p+1). E.g. 8932 * 8933 * 8934 = 712839893304 and 8933 is a substring. [Lava]
