There's one thing that I forgot to mention that we should probably do with the double-check drive: Report the ranges that we have searched that are not shown as searched up to n=260K at www.prothsearch.net in the 'List of primes for k < 300' link. That info. would be send to Wilfred Keller.

Here is what you do:

1. Go to http://www.prothsearch.net/riesel2.html.

2. Look and see how far your k's have been previoiusly reported as searched as far as the site is concerned. That range will be in brackets. For instance k=9 shows [200000] meaning that is the highest that anyone has reported the k as having been searched (regardless of how far it has ACTUALLY been searched).

3. If the search range shown is less than 260000, send an Email to Wilfred Keller at [ rz2a010 at rrz.uni-hamburg.de ] telling him that you searched from n=100K-260K and the primes that you confirmed. State your actual name when you do this like is done when you enter an ID for reporting top-5000 primes.

4. Wilfred will then credit you with having searched the range on his 'searched intervals' page at http://www.prothsearch.net/rranges2.html. If this is the first time you've reported ranges there, he will also add your name to the 'List of Contributors' at the bottom of the page. For k=9, he would show you as having searched 200000-260000 because someone else already reported it up to 200000.


There are 3 k's where we have now technically 'extended' the range searched as far as ProthSearch is concerned:

k=9 done by Mini-Geek. ProthSearch shows it at n=200000.
k=17 done by Flatlander. ProthSearch shows it at n=205000.
k=23 done by kar_bon. ProthSearch shows it at n=226600.

Tim, Chris, and Karsten, if the 3 of you can report the n=100K-260K completed ranges to Prof. Keller, that will help us help get that site a little more up to date. Be sure and include the primes that you confirmed in the Email. Thanks.

I reported a number of ranges to Prof. Keller when I did double-checking for RPS and it's a quick and easy process.

Whomever did the original searching on these k's at RPS or elsewhere failed to report their range so it is up to us to bring it a little more up to date since we're double-checking them.

The next k that will be 'extended' with this effort is k=33, which shows a search limit of 250000.

For the Riesel side, Prothsearch only maintains a page for k<300 so there's no need to concern ourselves with k>300.

My thinking on all of this is that EVENTUALLY (albeit a very long time), our threads here, the Primesearch site, the RPS k<300 page [if they ever decide to show it again (lol)], Karsten's/my k<300 page, Karsten's 300<k<2000 page, and the Prothsearch site will all be accurate and synced up and will reflect the ranges that have been actually searched for all k's. A huge undertaking I know but I like to think big.


Thanks,
Gary

Ok, I submitted the k=9 results to the email address.

[Flatlander]

Email sent for k=17.

Thanks guys. I don't think he needs results files. Tim, you could just send him the primes confirmed. But if you find that easier, I'm sure he'll be fine with that since he can check the primes from them.

I sent only the primes. Sorry I used wording that made you think I sent the full results.

Ok, cool. Thanks.

It will now be easier to double-check k<300. You can either refer to my updated k<300 page in the new thread by that name or as usual to Karsten's older k<300 page, which I think he should have updated sometime in Sept. I generally update mine about twice/week.

i sent my results/primes for k=21-25 to W.Keller!

Prof. Keller has now updated the intervals searched ranges here.

It's cool to see our faithful searchers names shown as assisting in checking these ranges. You can also see your full name shown at the bottom of the page under 'list of contributors'.

There are still many search gaps on the page for n<260K so when you have a spare core, grab a 3-k range, check it, and report your range to Prof. Keller if not already shown completed to n=260K!

The next range gaps that this double-check effort will fill are k=33 for n=250K-260K and k=37,43, 47, and 51 for n=210K-260K.

As we do the work for our new k < 300 drive, I/we will report the ranges done as a project. Obviously RPS has completely dropped the ball on reporting them. They were reporting them initially several years ago and then just stopped for no reason.

Not only does NPLB leave no primes behind, it leaves no ranges behind! lol

Hmm...I was trying to make sense of Prof. Keller's k<300 page just now, but it's kinda hard to follow--I can't even locate the list of double-checked ranges at all, just the first-pass ones. I'm sure they're hiding in there somewhere, though; could you please point me to them?
