 2009-08-04, 07:59 #301 em99010pepe     Sep 2004 2·5·283 Posts Cruelty, I few years ago I asked Bliss help for sieving k=223 from 2M to 3M but I only have the factors from 6.26T to 100T. Do you want them? I only ask people if they find a prime to share at least one with him. Carlos Last fiddled with by em99010pepe on 2009-08-04 at 08:01

From here 51, 57, 65 and 87 are only done to 1M. Why aren't you starting the sieve from 1M?

They have been fully tested to 1M. They have been sieved to 1.7M and partially tested already.

k=173 is complete to n=1017K, and k=263 is complete to n=941K. No primes were found for either k, and I'm releasing them. The results are attached below.
