If you decide to keep working on this k-value, we can add it to the low-weight stats page on 15k.org. At least that way there will be public record that you're working on it!

Curtis, that will be great. If it is possible to add it there please do so. I would like to credit RPS for any potential finding, anyway.

Dr. Broadhurst wasn't sure how far he test this k. He said that it would be best to assume that he stopped work on that k as soon as he found this...
http://primes.utm.edu/curios/page.php?number_id=526
(not sure what that mean, if anyone know please explain).

I will continue working this k up to 2M.

So, please include it in low-weight stats page.

Thanks.

I sent a low-weight update to Kosmaj just before checking the forum-- he'll get it on the server in a couple days. I hope/plan to update the page once a month, now that I understand how to edit the page without making a mess. Expect a mid-april update with your k-value as the bottom (largest) value on the low-weight page. I'll also add the k-values Thomas has referenced in his recent posts.

Post a reply when you've cleared the 150-220k range, so I can note that also.

One more reservation: 399239.
It produced a small prime at 253688 already. I'm running it to 1 million only on some slow machines.

I have checked k=177941, n from 1to 1M. Found only two primes:
177941*2^34-1
177941*2^154-1

I'm unreserving this k.

I already test K=2147483647 from n=2 to 150k and from 220k to 350k, currently work 350k to 500k range. Plan to do it up to 2M. I find only two primes, for n=97 and n=96001.

Range n=150k to 220k for K=2147483647 is completed. Range n=350k to 500k will be completed in a few days.

No new primes.

Here is a list of 31 k I'm currently looking at, and the primes I've found so far.
All have been tested up to n=475k, trying to reach n=1M sometime...
