Omission on my part on the pages. I've been so used to doing the Riesel side where b==(1 mod 3) has k==(1 mod 3) with a trivial factor of 3 so I inadvertantly omitted those k's==(1 mod 3).

So...9 k's are remaining on S343 at n=25K.

So I guess you're gonna make me search it to n=2500 to get all of the primes, eh? :-(

Please people, post all of the info. that I need for the pages. Thank you.

This isn't directed at you David but another pet peave is when a big prime or several (kind of) big primes are posted, the search depth for the other k's isn't listed. If that isn't posted, I can't update the last status date of the remaining k's. It's best if the search depth of remaining k's is >= to all primes on the base unless it is being searched by k instead of n-value; otherwise stating that xx # of primes remaining at n=xxK isn't quite accurate because larger primes have been found.

really it was the reservation i was posting
i was going to post the results when i was finished
here are the files
my current testing limit on k=6 is n=75k

When you post just a couple of primes and nothing else other than a search depth, I don't know what you expect me to show on the pages. It would be inconsistent to show only 2 primes.

Is it your preference that I just ignore your status in this kind of situation? If so, that is not a problem. But if not, I'll need at least the top 10 primes.

I guess I make the assumption that people are expecting their status to be shown on the pages within a few days of when they post it so I follow up to get any missing info.

Regardless, thanks for the primes.

feel free to ignore them
i just post early so that others don't do the same work

Gary, occasionally I have spare time to run several new CRUS bases. As long as I only post the results and primes of those searches 1 per day, is it ok if I reserve several in one day?

Unconnected,

Please only 1 new base per day. That's a permanent reduction from the previous 2 per day. I'll clarify this once more:

This refers to reservations of new bases. But if people just post the primes/k's remaining on a new base without reserving it, that also counts as a new base reservation in a day.

If you want to search 100 bases, you need to reserve them 1 a day for 100 days. If you want, you can do that and then post all 100 base's primes and k's remaining in 1 day. Obviously that's not ideal and would still annoy me somewhat but the "construct" of the base would already be in place on the pages and I won't complain. I would have already analyzed all pertinate info. that takes a little while; algebraic factors, GFN's without a prime, k's with trivial factors, k's that might have primes from other bases (such as base 6 primes that correspond to base 36), etc.

The idea here is to continually discourage the searching of new small-conjectured bases because it is not the direction that the project is intended for at this point.

See the above. No, that is not OK. You can post as many results and primes as you want on any day. You can post tons of them as long as they are not for new bases. Just do not reserve NEW bases more than one per day.

This is intended for many people here: What's up with this anyway? Why the fascination with new easy bases? It takes little effort to prove easy bases and shows little. Can someone please enlighten me? I still don't get it.

How about a new recommended effort: Whenever you have small snippets of CPU time, please consider starting the sieving of some conjectures with 1-2 k's remaining and eventually forward me the sieve file for posting on the pages when you feel it is near a reasonable depth (or even before so that I can coordinate having it further sieved). Maybe we'll eventually get a drive going where we search a bunch of 1, 2, and 3 k's remaining bases all together.

Hi paleseptember,

Thanks for the great work on extending the 1k remaining bases to n=50K. I noticed your pattern of going right up the bases 1 at a time on each side (Riesel and Sierp) for the ones that were unreserved and only searched to n=25K. Great idea and what the thread was intended for.

If that is what you are doing, don't forget Sierp base 230. It is the lowest unreserved Sierp base that has only the problematic k=4 remaining. A full 10 Sierp bases have only k=4 remaining so it's nice if we can eliminate one. I'm sure we'll find more bases where only k=4 remains also.


Gary
