Could one of the scripting experts do a list like "Unproven conjectures sorted by CK"? I just realised there are conjectures in the single-digit range e.g. R566 with CK=8 that are not finished yet and I am wondering what else is still floating around.

Vassilis (vmod) is our resident expert on scripting the pages

He has a script [url]http://www.noprimeleftbehind.net/crus/vstats/crus-stats.htm[/url]
that he may be able to add to.

Now that is a great page, thanks for pointing it out! It even answers the next question I was going to ask - highest CK that has been tested to at least n=25K.

S96 with CK=353081 is the only base < 100 with a CK < 1M that has not been searched to n=25K. Therefore I have added it as a new base to the recommended list and attached a file of the 1944 k's remaining at n=2500. It's above-average weight and I expect that it will have 550-600 k's remaining at n=25K so this is an ideal one for Ian or Peter. :smile:

 gd_barnes 2011-04-13 09:50

I've added R36 with 68 k's remaining for n=50K-100K. A link to an optimally sieved file (2.6T) is on the reservations page.

 gd_barnes 2011-05-29 22:33

I have added several bases to the recommended lists. Many already have sieve files started.

 gd_barnes 2011-06-06 06:21

The recommended list has been extended to include bases up to 256. This resulted in adding 4 new bases to the list.

One of them is an interesting one: R243. I'm not sure why but this one was stopped with 66 k's remaining at n=20K so I have recommended it for the small range of n=20K-25K. It's the only [already started and released] base that I am aware of that has < 1000 k's remaining and has not been searched to n=25K.

There is no plan at this point to extend the list past base 256 in the future although I/we may suggest general efforts for higher bases such as searching all 3 and 4 kers up to n=100K...stuff of that nature.

One note for everyone: Mathew has been very diligent behind-the-scenes about providing me with sieve files for many bases so that I can provide a link to them on the reservations pages; including almost all of the recommended bases. We have him to thank for a majority of the sieve files that are available on the reservations pages now. Thanks Mathew! :-)

Added S166 for n=10K-25K with 225 k's remaining.

The first post seems to suggest that all recommended efforts are reserved?

[QUOTE=Puzzle-Peter;274900]The first post seems to suggest that all recommended efforts are reserved?[/QUOTE]

They are. We keep it updated regularly. At this point in time, we are only recommending bases <= 256 and virtually all of those are now in good shape.

One goal that I'm considering setting for the project is to complete all bases <= 256 with CK < 100K to n=25K. I think there are 6-7 of them remaining and I have searched them all to n=2500 but don't really want to go further. I may add those new bases to n=25K in the next few weeks.

What??? Isn't S63 keeping you occupied? :smile:
