Prime-Wiki - Page 14

kar_bon · 2020-07-08, 15:14

I've included a table for the frequencies given by W.Keller for the Riesel problem.

The categorizing is done with the Riesel prime template (another addition!) but the Wiki still needs some time to determine the values.
It is not done if RCount is not set and only for k-values < 509203.

The same can be done for smallest even or odd n-values (Liskovets-Gallot) or other projects.

A FWIW: There are two links on the page https://www.rieselprime.de/ziki/Proth_prime which are non-functional. They point to the PSearch Project. http://mysite.verizon.net/wfgarnett3/ They time-out .

I bet that site is down. The project has been dead since 2006. https://web.archive.org/web/20140911...et/wfgarnett3/ is the most recent archived copy I found. Perhaps we should change the verbs to past tense?

You meant the PSearch page: I've edited the link to a new one (available here, and the Wayback page).

The problem with such links: I used the MersenneWiki data for those pages, only changed small things for including in the Prime-Wiki so some years old.
Wikipedia adds a date when such links were used the last. There's no automation to mark a link if it's not available anymore.

The page with listed projects is also outdated: Every project should get its own page (with project-template)... but where is my time?

Reference k = 6059.

I see some things were added, which is no problem. LLR found a prime less than the largest value, and greater than the two before. 130,136. Normally, I would simply strip-out everything in the sieve below the largest prime. In this case, I will not do that. If it found one below, there may be another.

Thanks.

Creating a new Riesel prime in the Wiki please:
- use always the current templates (see top link "Template prototypes") -> you missed the RCount parameter
- have a look at the RPPDb: Free-DC Drive #2 found the highest prime, the highest n-value is given as 50k
- please search the Top5000 page for any other entry for that k-value

There is still a chance that other primes for 50000<n<540968 could be found so do test the whole range then.
Information for Riesel (all k<100k with small primes, higher k-values special ones only) are available at my old pages or Top5000, just look there first.

I have a Riesel template here in the form of a plain text file. It did not have RCount in it. I just added it. I found the templates. Mine did not have RMultiRes. I added it as well.

I have links to some of what you mention above. I am not sure about RPPDb. UT Martin updated their page layout and I didn't recognize it, at first. I have a link for it as well.

k = 6059 continues. Closing in on n = 500,000.

kar_bon · 2020-07-22, 17:14

"RMultiRes" was added in Feb. 2020, "RCount" in May, that's why always use the Template prototypes and not privately copies.
Those're the current versions of prime number templates and you only have to copy/paste them to a new page.
The Wiki is still in contruction/test mode with many templates, but the Riesel prime template is the most elaborated one: some features are done the last weeks like the Riesel frequencies.
Some features should later be added to other templates like Proth.
RPPDb: The data shown for k=6059 says, this k was searched to n=50,000 and FreeDC Drive #2 found a higher prime (started from n=410,000 -> see menu for FreeDC and Drive 2 also).
UT Martin = Top5000: go to Search, put in the "Mathmatical Description" as "^6059*2^%-1" and select the "Type" option "all (includes unverified primes)" -> will show all primes there for Riesel 6059*2^n-1.

Would using something like https://www.mediawiki.org/wiki/Extension:Page_Forms help these issues?

kar_bon · 2020-07-23, 07:19

I know this extension, but it's more work in keeping current of all prime templates than the benefit of a formular.
As posted here the parameter will be used for speed up the tables display.
If all Riesel k-values got this parameter filled (~300 to go) I'll change the table display template.
By now there's only a hidden categorizing if this parameter is omitted but then an alert will be given (as shown in the other post) while saving such k-value.

There's seems to be a small issue on the Template Prototype page: where the table of contents is, instead of it reading "Contents" (like on every other page in the wiki that has a table of contents), it reads "Inhaltsverzeichnis" (which I am guessing is German for Table of Contents). Any reason why that is happening?
