GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) Add the prime factors of 94 and the result is 94 reversed. [Sladcik] 94 is the smallest k such that 2^{60} + 1  k is prime. [Russo] 94 equals the sum 2 + 3 + 4 + ... + 16 minus the sum of primes less than 16. [Sladcik] The smallest number k in which all the digits of k and k^{th} prime are perfect squares. [Wu] 94 is the smallest even number greater than four which cannot be written as a sum of two twin primes. [Capelle] (94!/49!)+1 is prime. [Patterson] 94 is the largest sequence (981270903981270996) of consecutive nonsemiprimes up to 10^9. [Luhn] The largest twodigit number n such that n!1 is prime. [Gallardo] The smallest emirpimes which, when concatenated with its digital reversal, gives a semiprime (a palindromatic semiprime): 9449 = 11 * 859. [Post] The last twodigit number to be the difference between two consecutive prime numbers (1100977 and 1101071). All other even twodigit numbers are the difference between two smaller consecutive primes. [Gaydos]
