GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) In January 1933 Adolf Hitler was appointed chancellor of Germany and before August of the same year Germany was declared a oneparty state. The smallest prime (emirp) whose the sum and the product of digits are equal to the same powers of consecutive primes (16=2^4, 81=3^4). Note that the sum plus the product of these digits is equal to the largest doubledigit prime (emirp). [Loungrides] The only year of the 20th century to divide a repunit prime with no more than 21 digits: 111111111111111111111 = 3 * 37 * 43 * 239 * 1933 * 4649 * 10838689. It therefore divides the repunit prime with 2*21 = 42 digits. [Post] Inauguration Day in the United States occurred on March 4 from 1798 up to the emirp year 1933 when Franklin D. Roosevelt was inaugurated President. Since then Inauguration Day has been on January 20. Furthermore, 3041933 (3/04/1933) is prime. [Green] 1933 = (1^{9} + 2^{8} + 3^{7} + 4^{6} + 5^{5})/5. [Wesolowski] 1^n + 9^n + 3^n + 3^n is a square for n = 0 or any positive integer. 1933 is the smallest prime number for which this is true. [Gaydos]
