GIMPS has discovered a new largest known prime number: 282589933-1 (24,862,048 digits)

+ The start of the first occurrence of three consecutive primes ending with the digit seven (1627, 1637, 1657). [Murthy]

+ The sum 2^(1/2)+3^(1/2)+5^(1/2)+...+43^(1/2)+47^(1/2) differs from the fraction 1627/(5^2) by less than 1/(2*10^5). Note that 1627 is prime. [Rupinski]

+ The last auroch (Bos primigenius) died in 1627.

+ The sum of the first 1627 palindromes is divisible by 1627 (242234268/1627=148884). The next such prime is 48337. [Gaydos]

+ The sum of the first three pernicious Honaker primes is a prime number. It is the smallest example of this form. [Bajpai]
