The sieve file attached to the first post here is missing the 2nd batch of k's. That is k=131, 133, 137, 139, 141, 143, 145, 161, 177, 181, and 187 are not included in the file.

Is this intentional? Am I missing something?

I see that k=187 had a prime in the n=2.170M-2.180M range. So perhaps the k's have not been missing for long. Is some sort of double-check needed for ranges higher than that?
