k's for last search

I just realized that I didn't include all of the k's that I searched in the last post. They are all of the ones marked in light blue for 8M < k < 12M on the summary page. But for future historical...

Low-weight primes for k=8M-12M up to n=100K

I decided to give one of my cores a 'break' last night from top-5000 searches and have it do some prime searches for all low-weight k's shown on our site from k=8M to 12M up to n=100K. Below is what...

57 low-weights for k=200K-1M missing & addl primes

Karsten,

I've held off waiting on a response from SB2 for long enough now. I posted 3 messages in this thread and sent him a PM over a month ago asking for additional information, all with no...

Low-weight k verification status

Karsten,

3 days ago, I completed an extensive search on 57 low-weight k's shown on our summary site for 200K < k < 1M up to n=100K. I found primes on all k's that are not being searched by Riesel...

SB2, me fill low gaps on 2 of your k's ?

SB2,

There are some gaps in testing at low values of n on 2 k's where the summary site shows that you have them reserved. But in looking at the thread here, I couldn't tell if you had intended to...

Starting points in testing

SB2, were you able to come up with those starting points in your testing for the 6 k's that I asked about?

Primes on top-5000 site for low-weight k's

In my verification efforts looking for missing small primes on low-weight k's on our summary site, I did a search of the top-5000 site on ALL low-weight k's from k=10K to 1M, since some of those are...

SB2, can you check and see where you started your testing on your k=239857, 248047, 306251, 320107, 334147, and 808477? I know you started where someone else left off at. It's just that I don't know...

That makes sense and is a very good point. We didn't have Karsten around at that time to post all of the primes somewhere. Cheers to Karsten! :smile: :flex: So we didn't necessarily post small primes...

Check all low-weight k's from n=0-100K

I feel compelled to mention this now because what is causing the problem is becoming increasingly obvious...

I strongly recommend that anyone who begins testing a low-weight k from where someone...

Specific starting point needed

Yes, it was clear that you're working down your list but that doesn't help us here. What we really need is for you to tell us exactly where you started on each k. We have no way to know where other...

SB2; clarification on starting point of testing

SB2,

Above is a partial quote from your last status report. Can you tell us where you started your testing? I ask this because in addition to how high you've tested, we also need to know where...

In the complexity of all of the situations involved in the various k's that I tested, I made a misleading statement in my original post about the missing primes. I attempted to correct myself with...

Be sure and check for small primes also

As you may know, I have done a lot of gap-filling and some double-checking on this site.

A couple of weeks ago, I noticed the unusual number of low-weight k's that have no primes listed, many...

Testing on 31 low-weight k's, missing primes found

I have tested 31 low-weight k's from k=10K to 200K up to n=100K that are shown on the summary page. This was a verification effort and not a gap-filling effort, although I did partially fill a gap on...
