Riesel 数和 SOB 项目的 Sierpinski 数很类似，只是k*2^n+1换成k*2^n-1而已。

Congrats to Footmaster....again...for hitting a prime. 462264 digits long and our 18th prime found as a project. This prime is ranked 21st overall of all primes ever found. Soon we will be breaking into the Top 20 primes ever found. Our next project milestone is finding a half million digit prime. Only 78 more primes to find!

A new DAT file has been released, with 58,617 fewer pairs in it. This should give users a small speed increase for sieving. It is available on the download page, as always. RieselSieve has discovered yet ANOTHER PRIME! It has been just a little over a month since the last prime was found. Congrats to everyone's hard work over at RieselSieve!!!
I checked the stats page today and I found this:
