I keep receiving error messages when trying to remove k values for which primes are known. Here are results at n=4.7k: PS forgot to remove second known prime for a k-value @n=2718,2719:
396524*331^2718-1
396524*331^2719-1

srfile -G -d "396524*331^n-1" sievefile.txt

Use the stop-on-prime option in your sieve file header when testing to prevent the continued testing of a k after a prime is found.

I will hold onto this file. Except to show the # of k's that are remaining at n=2500, I don't update the pages until the search reaches n=10K.

Have you read this post from our software/instructions/questions thread?:

See part 2 for info. about headers and using srfile to remove factors and k's with primes.

Note that if you have a files of primes, i.e. pfgw_prime.log, you can pass that as the argument with the -k switch to srfile. It will remove all n for each k in the file.

I believe you mean the -d switch. The -k switch removes factors.

Yes, you are correct. I always get them screwed up. I was actually thinking of making them interchangeable.

That makes two of us. I'm constantly mixing those up.

Finally figured it out...

...Unsurprisingly, I continuously made this mistake. 518 primes now removed, and a couple dozen found since.

Complete no primes, results attached.

I would like to reserve

update for R316, i'm at n=19200 (173 k test left on 2 core,419 k left atm)

If you can post the primes for n=10400-19200, I can update the status on the pages.
