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

+ The lesser member in a twin prime pair and exact anagram with the lesser in the next consecutive twin prime pair; the smallest twin pairs with this property. [Punches]

+ The smallest prime p such that p11 is equal to the sum of 11 consecutive primes. [Rivera]

+ The smallest prime of form 3^n+n, for n a composite, (n=8). [Post]

+ The largest of only three primes formed from the concatenation in order of two double-digit composite numbers differing by 4. The other are 3539 and 4549. Shall we call the pairs of composite numbers differing by 4, i.e., (35, 39), (45, 49), (65, 69), pairs of “cousin” composite numbers? [Loungrides]

+ The first prime Brady number.
