[QUOTE=grobie]I suffered a setback, I just bought a new box and 3 weeks later the hard drive crashed, its going to be replaced by dell, but for my k=1222853775, I lost all testing and sieve file from n=10k to 250k, I think my testing was at approx. 176K. My second box is still testing 250k to 300k.
Should I sieve & test from my last prime or start at 175k. All of the llrresults are gone also.[/QUOTE]
Ok, hard drive installed, NewPGen is now sieving again from 175k to 250k

Small update: still crunching on my 2 k's:shock:

I've run all the candidates for n=0-50k, added some more Ks, and
updated the table. My hope in expanding the range from 10k to 50k
is that the candidates will be a little more predictable.

Reserving k=317372055

Reserving 1501946985

Status of my search:

234686595 tested up to 135k=> 102 primes
360949875 tested up to 135k=> 100 primes

reserving 555567045

555567045 is all yours - good luck!

Thanks!

Just two questions. Should I use LLR 362 or some other (once I'm done with sieving)?

Is there a way I could find out how many digits candidate of the form k*2^n-1 has?

Edo

The number of digits is log base 10 of the number which comes out
to roughly 0.3*n. To get onto the top-5000 n must be at least
220k now.

I'd stick with LLR 362 unless we find something reproducibly wrong with it.

Thanks.
