Team drive #12 k=2000-3000 n=50K-425K - Page 7

Hum. That's strange. By the Emails that I remember seeing, the manual results for k=300-400 for n=600K-1M were imported long ago, yet the graph shows almost nothing for the range. Max, what's up with that?

They're in the database, but the code that generates the graph has not yet been updated to include that range.

Just in case this server is about to dry:
I'll have 4 cores on this until I get bored again.

Thanks for the heads-up. There should be plenty of work in there to keep 4 cores busy for quite a while, but I'll keep an eye on it just to be sure.

Thanks for chipping in Chris.

Looks like 2057*2^345230-1 is a missed prime? Or maybe the test limit of 350k was wrong?
Recently found primes
Primes from k=2000
NPLB, right?

In 2006-2007 T.Ritschel tested the range k=2001-2599 (for most k not divisible by 3) and gave a testrange of n=200k-350k.
I've to look for that post, but he submitted many primes at the RPS-thread POST LOTS AND LOTS AND LOTS OF PRIMES HERE.
See the outdated page I've compiled those days here.

I've also found some missed primes in this range and Thomas got no results anymore to verify. So perhaps there're some more primes not known yet!

PS: IIRC there were also some missing primes caused by issues with LLR 3.6.2.

Hence why we're re-checking all k's in the k=2000-3000 range in the 12th Drive.

2069*2^257024 is prime. Too small for Top 5000 list.

For this drive, you don't need to bother reporting the small primes you find; none of them will be top-5000-worthy and as such the plan is to itemize them all at the end.

Reserving k=2200-2400, n=250K-350K for port 7000. (It's not quite ready to dry out just yet, but it will be getting there soon, so I figured I'd do this now so I don't forget.)
