1785*2^646070-1 is prime The 72nd prime for the very prolific k=1785. Edit: k=1455 that Brian just found a prime for is even more prolific; now with 78 primes. LaurenU2 found a nice pair: 1627*2^647673-1 is prime 1431*2^647763-1 is prime LaurenU2 went on one of his patented runs: 1575*2^648997-1 is confirmed prime 1757*2^649008-1 is prime 1877*2^649526-1 is prime 1791*2^649689-1 is prime 1985*2^649728-1 is prime That's amazing for such a large n-range!  Fozzie found: 1745*2^650260-1 is prime LaurenU2 found: 1991*2^654810-1 is prime 1559*2^655252-1 is prime LaurenU2 found: 1635*2^656285-1 is prime LaurenU2 found: 1793*2^656912-1 is prime Fozzie found: 1505*2^657540-1 is prime LaurenU2 found: 1815*2^659158-1 is confirmed prime 1495*2^659159-1 is prime LaurenU2 found: 1617*2^660752-1 is prime Helix-Von-Smelix found: 1573*2^662203-1 is prime The prime was reported incorrectly at top-5000. I am in the process of getting it corrected. I confirmed my own prime: 2145*2^425089-1 is confirmed prime 2507*2^425734-1 is prime 2425*2^426537-1 is prime 2477*2^427220-1 is prime 2183*2^427880-1 is prime 2565*2^427924-1 is confirmed prime 2569*2^428333-1 is prime Last fiddled with by mdettweiler on 2009-09-21 at 02:40 Reason: merged (cleanup) |
