[QUOTE=Retep;292620]I started to test the range k=51, n = 2.5M to 3.3M at 19 Oct 2010.

Nearly 80% finished, no primes.

I plan to continue beyond n=3.3M if there is no prime in this range and will hopefully find a large RPS prime.

My computer is a suboptimal solution for the sieving, would anyone consider to support me for the range n = 3.300.000 to 5.000.000?[/QUOTE]

Primegrid have already sieved all k < 10000 for n < 6000000. The files sieved to p=110000T can be downloaded from [URL="http://uwin.mine.nu/sieves/rsp/sievefile/"]here[/URL]. The files you want start with rsp3M, rsp4M and rsp5M. You can extract the individual k's with srfile.

Attached (I think?) is 51 from 3M to 4M. I had the 13 Dec file on my machine- so this file is sieved "only" to 100T. The current file is to 110T.

So they still continue to sieve all k < 10000 for n < 6000000? In this case I will wait until I finish the first range and use the current data in summer.

Thanks for the information.

They stopped sieving n < 3M at p=100000T, but 3M < n < 6M is still being sieved and is currently at p=131000T.

Whoops! I meant "P", not "T". The file is to 100P = 100000 T. I think Amphoria cleared this up, too.

Working on k=39 from n=1.7M-2M.

k=165 complete up to n=2.83M, continuing.
