GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) 124 is the smallest number whose sum of digits as well as the number itself are one less than the cube of a prime. [Gupta] The sum of the 3^{rd} to (2*5)^{th} prime numbers (5 + 7 + ... + 29 = 124). [Thoms] 124 = sigma(1!*2!*4!). Note that 124 is the smallest multidigit number with this property. [Firoozbakht] The concatenation of 1^124, 2^124, 3^124, 4^124, 5^124, 6^124, and 7^124 in order is a 463digit prime number. [Gaydos]
