GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) (274  2)^{2} + (274  7)^{7} + (274  4)^{4} is prime. [Opao] The 274th Lucas number plus 274 is prime. [Opao] 4^4*14^14*274^274 + 1 is the largest nontitanic prime, (687digit), of form 4^4*14^14*274^274*…*a(n1)^a(n1)* a(n)^(a(n)+1, where the bases and exponents are composite, a(n) and 4^4*14^14*…* a(n1)^a(n1)*a(n)^a(n)+1 are prime, a(n)>a(n1), and a(n) is minimal. Note that the previous such primes are: a(1) = 4^4+1 = 257 and a(2) = 4^4*14^14+1 = 2844673747342852097. [Loungrides]
