Taking 34K-35.5K.

edit:
(I won't bother removing the found ks, it would only save about an hour.)

Good luck. You're doing a really great work.

@all: I managed to find the mentioned primes, that you've all found during searching on this conjecture. This means that on my website, for now 21 primes with n>25000 has been added to en expectively growing list. In the future, maybe near future, I expect to make an addition to this list so one can see which other primes this specific k produced

Remember to be on the list, it doesn't has to be a Top-5000 prime. Only demand is that the prime mentioned is having at least n=25001 as its power. So feel free to check back occasionally to see if I've seen your prime and managed to add it to the list

Regards

KEP

Ps. I'm really glad that you all do such a hard effort to knock down some k's, it makes my dream of at least for the Riesel base 3 conjecture, to reach n<=50M, so much more easy to realize, though it is a hard dream to realize, I'm sure it's possible

Have a nice fight everyone

How many are you 'expecting' for this drive?

With Sierp base 3 as the indicator and from my experience on testing n<25K, as a general rule, we've seen just under half of all k's eliminated with each 4-fold increase in the n-value.

Therefore, with 434 k's remaining to start the drive, we should get somewhere around or just over 200 primes out of this effort.

All k's with primes have been removed from the files.

I also posted already reserved files with k's removed that have lower primes or primes that are within the specific file. k's with higher primes remain in the files in order to find the lowest prime for each k.

A batch file script that I have makes the removal relatively easy.

another lot of confirmed primes

my lower range has jumped up the fft barrier so the testing times are now similar

I'll be testing these with Geoff's new Linux build of phrot 0.51.

Is phrot quicker then? (Windows 32bit)
If so, where can I get it, how do I run it?

I suppose so.
You can get it from here.

Running the client is explained here.

BTW, this topic shows all discussion about phrot compilation and setup.

Thanks, I'll check it out.
