Which siever do you use? NewPGen?
You've missed the prime for n=4 here. Please use srsieve, bacause NewPGen loses small primes < ~20.

Please check for twins, too.
How to?
Change the header of the LLR-ouput file (which contains all primes of Riesel type) from like "283198073:M:1:2:258" to 283198073:P:1:2:257"" and run this as LLR-input again.

Thanks.

Yes, I can see why, newpgen must not check the sqrt(n) limit before doing modulus tests.

Thanks, Ill do this in the future. Also, register my name in your website as "W. Byerly"

all k's were tested in the range n=400k to 1000k
Karsten,

Did the primes really "stop" coming at n=519716 on a search to n=1M for so many heavy weight k's?

No. Some of those k-values were done in the RPS 9th drive up to n=1M.
The others were done by Beyond alone (prime to about n=640k are listed on my pages) but I've never heard any results or ranges done from him, only the primes in the Top5000 I know about.

So as many other k-values in the 3000er or 9000er range no searched range info is available.
It's a hunter, not a collector!
