Default k=105

We are going to continue primality tests of 105*2^n-1 started by Flatlander who stopped at n=541,300 as he kindly made his sieving file available. The file goes to n=1.5M and is sieved through p=4.2T. I already sent one block to B'maxx and will do one by myself. Curtis is sieving from 600k.

BTW, the 200-500k range was tested by Jeffrey a few years ago, who found 5 primes in that range. For details refer to our k<300 stats page.

The sieve is approaching 10T. I'll send new files to Kosmaj when I reach 14T, in ten days or so.

I'll gather up my sieve files and send new ranges to Kosmaj in a day or two. They will be sieved to 12 or 13 T.

Files in the 630-700 range sieved by Curtis to 13T are now available for download.

B'maxx is taking 630-650, so there are only 5 more to 700k.
