Dense k=287626
Good find! That prime will remove more than 1% of the remaining Riesel tests.

It has been a while, but I finally knocked another one off. So far this is the biggest prime on the Sierpinski side.
71098*5^319336+1 is prime! (5864.2514s+0.0470s) I'll submit it to Prime Pages later today. BTW, why is the Prime Announcement thread closed? Last fiddled with by rogue on 2008-10-06 at 14:28 |

Only moderators are allowed to post to the Prime Announcement thread. That thread was setup before I became a moderator - I just copy any prime announcement here to that thread; kind of redundant, I know. |
