k = 17851 reached n = 500k, and the primes and residues were posted in the "Post small primes..." thread. I am releasing this k.

k = 1501946985 reached n = 100k, and get primes:
1501946985*2^526131 1501946985*2^678321 1501946985*2^805771 1501946985*2^840241 1501946985*2^865441 now going to n = 200k

For lack of a better place to post my ongoing reservations, I'll dump them here. The mods can move this post if necessary.
I'm reserving:
All of these reservations, except for the RPS drive k's, are either already up on PrimeWiki or will be shortly. The RPS drive k's will be posted along with the data from the respective drives at a later date.

I'll also tack on k=14549535 for 125k < n < 300k as a doublecheck.

Q.: Is there a good generalized way to search for available k's?
This is what I do. I will use "9999" as an example. I will do an entire forum search for "k=9999." Then I would follow that was just "9999." If there are a lot of hits, I look at each and use my browsers' "Find on this page" feature to search. I check the "Top 5000" web site, and the Wiki Riesel Prime database. RPS appears to stay below any Nash value < 1000. It is hard to determine what their k ceiling is at any given time. NPLB, it is difficult to see what they are working on. That area is not updated often. After all this, if I find nothing concrete, I assume any k I search for is fairgame. If there are other places to look, I would like to know what they are. Bottom line: I do not want to step on anyone's toes by running something another person is working on. End of story...

Take any k above 10001 and I am sure 99% you will not in that case step on anyone others theritory
Also you have other base then two and software to make sieve for any home project. In other words, you have near countess combination, choose one Last fiddled with by pepi37 on 20200325 at 17:16
