GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) In 1917, Ramanujan gave a short list of odd numbers which cannot be written as x^{2} + y^{2} + 10z^{2}. Eighty years later it is was shown that 2719 is surely the largest such number (GRH). Did you notice 2719 is a permutation of the HardyRamanujan number? [Ono1997] [Beedassy]
