I'm willing to help you sieving. When you're done just send me a PM.

I will add k=201 from n=1.2M @ p=2T.

Cruelty · 2009-07-31, 11:56

k=25 tested till n=2.21M
k=43 sieving
k=59 tested till n=3.11M

k=101 tested till n=2.02M
k=151 tested till n=2.02M
k=233 tested till n=1.28M
k=283 tested till n=1.28M
k=299 tested till n=1.28M

I am still working on those.

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

Sent. Enjoy.

k=7 at 2.3M

k=21 at 1185k (including 1140-1181 completed by pb), a new prime found last week at n=1182083

k=35 at 1720k (including 1550-1715 completed before with help from Beyond and Cruelty)

k=79 at 1060k

Releasing k=177 at 1280k

Taking k=139 from 800k

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

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

Yep, that's what I was told

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.
