Prime-Wiki - Page 15

Perhaps you use "German" as page language? You can change this by choosing "English" in the top menu. And possibly have a look at your "Preferences": Internationalisation.

Try a "Purge" also.

Looks like it is fixed on my end now: just had to select English again in the top menu (it was selected before, so I am not sure why it wanted to put that in German. Maybe a caching issue).

Happy5214 · 2020-07-26, 08:37

I had also purged it, so that may have also helped.

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.

RPPDb I think I found, but it says it is no longer maintained. It is here.

I did a forum search for FreeDC, but did not find anything specific. Perhaps my search was too broad.

Searching UT Martin yields a lot of data once the parameters are correct.

RRPDb: What is not maintained where?
The link you gave is the home page with the menu/links to all different prime page I've designed the last 13 years.
The page for 6000<k<8000 is still there and will remain until I moved all data to the Wiki.
FreeDC got his forum here (the Prime Search can be found here with their 3 drives) and an overview of the drives at RPPDB is also available.
I don't know what browser you use or what you see but this is the available menu on RPPDb:

It appears I misinterpreted the line at the top of the front page. (Attachment). "Not under my control." My apologies. There is a lot there to move. Until then, a good reference.

I did my search for "FreeDC" and not "Free-DC." I had never seen this site before.

My browser is Mozilla Firefox.

What I see, cannot see, or cannot see correctly, is not a topic for discussion. I was browbeat because of it and I do not wish a repeat.

On the old Riesel Prime database site you had marked k's that are primorials (for example, 255255 was marked since 255255 = 17#/2). Will this be added to the wiki?

kar_bon · 2020-07-27, 20:36

This is possible by using a special category, because of the few k-values an automated recognition is not needed.

There are some problems:
- k=278970415063349480483707695 = 71#/2 the automated calculations of the 3k/15k/2145k/2805k values are not correct and will shown in those table falsely (see last entry of this table). This calculation has to be done in another matter or anyway.
- Those long k-values will broaden some other tables until there's no other possibility.

I can create an own category, a page with table and the first few values.

In Riesel prime 5110664609396115, n=143 is also Sophie Germain (not only n=34944 and 34945)
Done.

kar_bon · 2020-08-01, 19:15

I've implemented a recognition of missing markings of Sophie Germain in Riesel prime pages and found 6 more.
The algorithm is testing
- only for Riesel primes
- only if such page was saved
- not in any table view
If a missing value is detected, the page is categorized
Perhaps there're some more but the system has to check all which takes some time.

Some changes in handling MultiReservations for Riesel values:

If a project reserved several k-values a MultiReservation will be used to handling easy range or dates changes during that project: change only one value instead of editing many pages.

The problem before: If the n-value range is not set to n=1 but instead of say n>=400k and the lower ranges are not yet tested, the max n-value shown in any k-value page of the project is false.

Solution:
If a MultiReservation of a Riesel k-value is set and a max n-value (RMaxn) is given, the RMaxn value is shown including the MultiRes n-value in brackets.
The categorizing into the Missing range category is set, too.

Example:Riesel k=15373 reserved by RPS Drive 10 which reserved for 400k<n<2M and the lower range 300k<n<400k is missing right now.
The display in the table are not yet changed (later to do).

More:
- All missing RCounts inserted in any Riesel k-value pages and so this value is used to be shown in the tables
- The display of the k-type has changed: for example a 2145k-value is linked to that page with table
- Many k-values from the Riesel problem were inserted and the table of frequencies showing which values are complete
- Many Riesel k-values inserted and the original RPPDb pages are updated (deleted those values there but including a link to the Wiki).
