That gave me a grand and glorious idea: Start sieving k=2000-4000 for n=10K-600K! n<10K is already done.

Anyway, to answer your question, you could reserve them here or at Riesel Prime Search (RPS). Preferably here. :-) Just post that you're going to reserve a k or range of k's. Karsten picks up reservations from both projects. RPS would have as much sieving done in that range as we would; that is little to none. If you post a reservation for that area here, I'll create a new thread for work done or reservations k>2000 and move your post there.

Would you like to run some individual k's or a range of k's in that area? If so, let me know and we'll team up on some sieving.

So...what does everyone think of my grand idea? That's an area where well over 90% would be new primes!

I like that idea, too. Though, I think we should wait at least until we're somewhat closer to the end of all our k=1005-2000 work; we're already very, very busy right now with loads and loads of work to be done, and adding yet another very large k-range at this time would spread us too thinly, IMO.

However, yes, we should definitely look into tackling that range once we're farther along on k=1005-2000; even though it's not quite as messy as 1005-2000, 2000-4000 still could use some of that cleaning up that is NPLB's specialty.
