Riesel base 6 - team drive #4 - EIGHT OR BUST!

[gd_barnes]

We are starting Conjectures 'R Us (CRUS) team drive #4 for Riesel base 6 starting at n=150K and continuing until all k's have a prime or we just get tired of searching! Included in the drive are all remaining 8 k's that need a prime. We have now found 7 primes so there is only 1 k remaining. It is k=1597 with a weight of 272.

The file has been sieved for n=1M-2M. The sieve depth is P=180T. As we find primes, we'll remove k's from the file for higher n-ranges.

This is a very exciting drive. With such a low base and so few k's remaining, we have a very good chance of proving the conjecture over the next few years.

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=1.5M-2M.

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. Individuals are now testing higher n-ranges.

Let's blow away the final few k's!

Reserving first file. (not sure of its n's, one of the mods here can edit this post with the range after you know it, if you want)

That would be 150K-155K. I've sent Gary instructions for uploading the sieve files to the http://nplb-gb1.no-ip.org/ server, so he should be able to get those up next time he's online.

The files are in n=5K ranges, which I'm sure you'll find to be a good size. All files up to n=200K are now posted.

Let us know when you have the file and we'll remove it from the 1st post here.

Taking 155K-160K

[Mini-Geek]

I've got the file.

[Flatlander]

Taking 160-165.

(8 or Bust. Cool!)

Haven't you got that backwards?

No, that's the way all the other drives have done it for quite a while. Early on, we did them from lowest to highest, but then realized that didn't take long to become a pain in the butt: as soon as the table fills up the heigth of the code box, then you start having to scroll down in order to see the newest stuff. Much easier to put the newest stuff on the top.

I like that. I'll put that in our thread name.

[Flatlander]

I was hoping you would.
