Default Sierp base 6 - team drive #3

We are starting Conjectures 'R Us (CRUS) team drive #3 for Sierp base 6 starting at n=30K and continuing until all k's have a prime or we just get tired of searching! Initially included in the drive were 50 of the remaining 56 k's that needed a prime. We have now found 45 primes so there are 11 k's remaining, all of which are in the drive. See the Sierp base 6 web page for the k's remaining.

The file has been sieved for n=400K-1M. The sieve depth is P=130T. No more sieving will be needed for this range. Many thanks to Lennart for sieving P=25T-130T.

We will be running the remainder of the drive on CRUS PRPnet server port 1400. The server will hand out the final range of n=700K-1M.

Instructions for running a PRPnet server and download links can be found here. The info. specific to this server that needs to be entered into your prpclient.ini file is:

server=G1400:100:1:noprimeleftbehind.net:1400

All sieved files have been tested. Eventually we will begin sieving a higher n-range.

Let's blow away those stubborn k's!

I'll reserve the first range of n=30K-38K to get us started.

Found PRP by LLR, proven with PFGW:

37815*6^39336+1 is prime!

BTW: At what n-value does this drive enter top-5000 territory?

Assuming a now-median k-value of k=90546 and the current 5000th place prime of 26267432109*2^333333-1 as of 3:10 AM EST US on 2/3/08, it would be at n=128958.

Of course it might be a smidge higher when we get there. It might actually be n=128960 or something.

Well, it looks like we have our work cut out for us, then!
