Thanks Max.

Serge, I still need to know if you are keeping R1011 reserved. In cases where you don't specify a limit, I'll go ahead and assume that you will not be taking it further.

If anyone happens to read this, I'm completely ignoring my PMs and Email until I finish all of the updates here, which I'm finally hoping to finish tonight.

25K, all of them. It's a default.

If I reserved something and didn't unreserve, then they are reserved.

So are you keeping any of them reserved? That was my question in the last post for R1011.

That is very confusing. You've got me really lost now. What if you say so-and-so base has 3 k's left and give no other specifics? At first I thought you were keeping them, then I thought you weren't, now I think you are but am still not completely sure on those bases that you gave no specifics. I keep changing the pages one way and then the other and now I'm going back again and it keeps taking me longer and longer. I'll tell you what. I'll have the pages all updated within 30 mins. of this post now. Please look at them and see if I have your reservations correct.

I also have to reflect them correctly in the 1k thread, which adds even more time.

With 40-50 new bases over the last week, I'd appreciate specifics on each posting like: "Complete to n=25K and continuing to xxx" or something like that.

If we didn't do another new base for the next year, I'd be perfectly happy. lol

Thanks.

The "3 k's left" message was already an update. The originals was above it:

Some PHP or perl-cgi based automation could do wonders to your (already wonderful) webpages. Don't you see that you turn yourself into a human-power-driven CGI? And from that CGI-like behaviour stems your frustration when people are not specific enough. I can understand that. Sorry, but the best way to restrict the vocabulary and remove ambiguities is a set of simple forms:
[code]User [......] Email [as a weak authentication + for the followups]

Reserve {Riesel|Sierp} base [...] from n= [1|default] to n=[25000|value]. [Submit]. [I]=> return a four-digit reservation "code"[/I]

Release {Riesel|Sierp} base [...]. Release code: [user can insert old [I]"code"[/I] here to prevent poaching]

{Riesel|Sierp} base [...] is proven. [Browse file=...] [Submit].[/code]
See M.Kamada's site for a prototype. It is not awfully hard. I think manual editing of pages is way harder and [I]'makes[/I] you hard' (quote from the [URL="http://www.chicagotribune.com/news/columnists/chi-schmich-sunscreen-column,0,4054576.column"]fake Vonnegut's address[/URL] to the class of '97.

Don't get frustrated. Simplify it.

I was going to suggest a very good base, but now I am not sure.
I honor your moratorium. Anything but a new base! :-)

Peace! -Serge

BTW, you still haven't clearly told me if R1011 is STILL reserved. Is it or not?

Feel free to suggest a very good base. Assuming it's new, I'd only ask that you/we wait a week to work on it because I now have a lot of time that I need to spend on the NPLB project. It has gone dormant.

I'm in over my head here right now. I fully expected this project to stop at base 100 with some bases that are powers-of-2 up to 256. Since the Riesel and Sierp k listings go up to 1024, I subsequently expected that we would slowly work our way higher. The new bases script was intended for me to be able to easily doublecheck existing bases and allow people to fill in the holes on lower bases and very slowly work our way higher. Instead it has been used to search them everywhere; 10's of them at a time. The fact that the most complex small conjectures are now being searched en mass is what is causing the problem.

I was a legacy programmer for years, completely burned out, and frankly don't want to learn a lot about programming/web design/etc. I know just enough about updating the pages to keep them up to date. I did not know HTML at all prior to 3 years ago. I have no idea what CGI is. I Googled it and got several different things that it could be: CGI programming (i.e. a language), computer-generated imagery, common gateway interface, etc.

If there is anyone out there that can completely design and interface what you are talking about with the pages and has the time to do that, I'll step aside.

One thing that I don't want to get into: A situation like the former PrimeSearch project where they just had an automated reservation system with little communication and expiration of dormant reservations and little checking of ranges to make sure they were correct. That did not work well at all. Automated reservations are great but there has to be communication about statuses, etc.

R841
 

I agree with you on many of these points. No hard feelings?

1. R1011 is still reserved to 25K.

2. Reserving one last interesting (and surely challenging) base R841 to 10K:
- conjectured [I]k[/I] is 24090, ...[I]but[/I]
- because [I]b[/I]-1 = 2^3*3*5*7, many (6539) trivial eliminations, and that's not counting odds,
- 5364 primes - a [I]very[/I] prime base,
- after the script, at n=1K, there were 138 k's left, of which 10 are squares and eliminated,
- base is 29^2, too (though R29 doesn't help here, because it was a very short conjecture), but testing is faster than neighbors,
- at n~=4300, another 68 k's are eliminated, with only 60 k's remaining (out of 24090!).

I'll email you the report (it's too big for the forum's margins to contain), but I'll give you (and me) a few days to rest, ok?

Have a good weekend!

-Serge

Of course no problem. That is an interesting base.

BTW, the pages are fully up to date now on my end. One minor problem: We just had a server move and there is some port forwarding stuff that needs to be taken care of that I don't deal with. So you'll need to look later today for the updated pages. The pages that can be viewed right now are about a day old.

I have fully updated the 1k thread as well as the untested Riesel and Sierp bases threads. You might check some of your reservations in the 1k thread.

Riesel Base 639
 

Riesel Base 639
Conjectured k = 2136
Covering Set = 5, 7, 19, 499
Trivial Factors k == 1 mod 2(2) and k == 1 mod 11(11) and k == 1 mod 29(29)

Found Primes: 905k's File attached

Remaining k's: 24k's File attached - Tested to n=25K
k=4, 64, 324, 484, 1444, and 1764 proven composite by partial algebraic factors
k=1136 proven composite by a difference of squares

Trivial Factor Eliminations: 131k's

Base Released

Riesel Base 744
 

Riesel Base 744
Conjectured k = 299
Covering Set = 5, 149
Trivial Factors k == 1 mod 743(743)

Found Primes: 278k's File attached

Remaining k's: 11k's File attached - Tested to n=25K

k=4, 9, 49, 64, 144, 169, & 289 proven composite by partial algebraic factors
k=186 proven composite by a difference of squares

Base Released

Riesel Base 821
 

The conjectured k is 958.

106 k have trivial factors.
351 k have primes with 140*821^24442-1 as the largest found (so far).
21 k have no primes.

The hiddenpowers script gave this message:

144*821^n=0 mod 2 factors due to 12^2

Clearly that removes k=144 when n is even, but uncertain about when n is odd.

This base is searched to n=25000 and is released.
