 2020-08-05, 05:56 #423 gd_barnes     May 2007 Kansas; USA 237008 Posts PrimeGrid will continue their work on the two Sierp base 2 even k's. We will remove tests for n>6.625M from our PRPnet server port 1400 and PrimeGrid will take it from there. The k's are: 90646*2^n+1 101746*2^n+1 I will eventually post a link to PrimeGrid's status page for these two k's on our web pages. Last fiddled with by gd_barnes on 2020-08-05 at 05:56
