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 20090804 at 08:01

Carlos,
Please send it to me (I'll PM you my email address). I'll sieve the missing part below 6.26T and hopefully find a prime to share it with Bliss

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.
