4000 < k < 5000
 
I've decided to start working on the range 4500<k<5000 (sieved to p=3P) with some cores I have available right now.
My plan is to do it in several drives.
In the first drive all k's will be searched to n=120k (work in progress). The next drives will extend the range stepwise depending on core availability.
All k's have been tested to n=20k, but this range will be DC. Some k's have been tested by others on some higher n's, leaving a gap behind in most cases that is planned to be filled:

J.P.Burt
k=4515, n=191k-284.1k
k=4559, n=500k-1.0M
k=4589, n=500k-1.0M
k=4601, n=500k-1.0M
k=4691, n=500k-1.0M
k=4717, n=500k-1.0M

C.Chatfield
k=4779, n=?-?
k=4851, n=350k-384k

RPS 8th drive
k=4935, n=380k-

k=4597 and k=4813 were already searched to n=1.0M (J.P.Burt) with no gaps and initially will be only DC to n=120k.

I am on my own in this quest for now, but if anyone wants to join I could post the sieved ranges.
Lots of primes are to come!

You can find [URL="http://uwin.mine.nu/rsp/sievefile/"]here[/URL] the k's 4 < k < 10000 sieved to n < 6M.

Thanks pepe, in fact, those are the sieved candidates I am using.

That's me.
Sorry, I don't remember what I did 4500<k<5000. I also can't find any residues for anything in that range.

No worries, it would have been good to have some DC. In any case, thanks for checking.

Status: Finished 4500<k<4590 for n<120k.
Total: 1141 primes.

I've just updated the 4000-5000 page with the new primes for k=4500 - 5000, n=20000 - 200000.

Thanks otutusaus.
