287626*5^2771751 (193743 digits) is prime

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?

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.
