Thanks for the primes Lennart.

What is your current test limit for k < 2M ? I'm asking because I still show it at n=120K, which is lower than k=2M-10M.

1-2M is at 350k

2M-10M is at 150k

10M-20M is at 50k

20M-30M am I now working on at 20k

Lennart

I would like to reserve S7 for k's 1M-5M to n=25K

S7 k's 1M-5M complete to n=25K

62 k's remaining

Attached are the remaining k's

Additional results emailed to gd_barnes

Taking S27 for a spin from n=400K to n=1M.

[QUOTE=MyDogBuster;265796]Taking S27 for a spin from n=400K to n=1M.[/QUOTE]

I did the sieving on this one for n=250K-1M to P=35T. It is sufficiently sieved for n<=500K. If you need to test n>500K, it will be more efficient to do more sieving.

Ian has reported that R27 is at n=~800K.
