 R63 tested n=2001 to 10000. Files sent to Gary. 504736 k's were eliminated, 299255 remain. Base released.
I'm impressed. Great job Peter

I don't understand. Since it is proven, why would you care to test for k up to 50000? None of the results would be useful for this project.

You can use the script.

Crazy stuff! Awesome work!! On average, there were more than 15 k's being removed at each and every n-value and no less than 17 k's were removed at exactly n=10000.

I probably won't be working on this for about two months, but as I will be away from home for most of the month of August, I need to reserve now so that I can sieve and drop into my server before I leave just in case I get lucky and find a multiple R30 primes in the range I'm working on.
