GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) The smallest brilliant number that contains all three brilliant digits. [Gaydos] The smallest 3digit brilliant number formed from the concatenation of composite digits. Note that its prime factors, (11, 59), create another brilliant number, 1159=19*61, whose prime factors create a third brilliant number, i.e., 649=11*59, 1159=19*61, 1961=37*53. So, 649 is an "extrabrilliant number." [Loungrides]
