Wow, S938 has 49 remaining k at n = 1000. With a conjectured k of 314, this is absolutely nasty. We'll see what remains once I get to n = 25000.

The 2nd worst (and worst still open for reservation) is R878 with a CK=292. It has 56 k's remaining at n=5K. There is nothing else even remotely close to these 2 bases for any CK < 1000; and that includes bases that have already been reserved and/or tested to n=25K. They are why I choose to test upward by # of k's remaining at n=5K instead of CK. Most of the low-lying fruit has now been tested or reserved. |

Ian has already tested S628 to n=25K. See http://www.mersenneforum.org/showpos...&postcount=955. Sorry...I guess we didn't get it removed from the bases remaining to be tested list when it was reserved previously. Edit: One thing that I thought was strange on this that I just now noticed: You said that these 4 bases take care of all Sierp CK bases < 1000. S628 has a CK = 1072. Did you mean some other base?

I had four cores, so I chose four bases. It was just easier that they were all Sierpinski. |
