Hi @all,

I'm collecting for about 3 1/2 years now all primes of the form k*2^n-1 (Riesel-side, see also http://www.rieselprime.de).

As PG is crunching and finding more and more the Proth-side (k*2^n+1) I've decided to collect and create pages for those, too.

For the first step I've used W.Kellers page www.prothsearch.com for 1<k<1200 and n<640k.

PG now has done much work and also doublechecked a lot of ranges and k-values but I'm missing some detailed information here.

At http://www.primegrid.com/stats_pps_llr.php it would be helpful to see:
- n-range of search done
- primes found (n-values)
- prime is new or confirmed (doublechecked)

After reading this forum I found the lowest range for 1<k<1200 at n=200k. All other k-values the n-range seems quite higher (~500k).

The search for lower primes n>=100k for k>1200 at PPSE is also rare of result-information:
- Which n-ranges were searched?
- List of primes found
- New / confirmed primes

I know about 13400 Top5000 primes of PG, about 6200 conf./new at Proth-type.

Question:
If a non-Top5000 prime is found, where can I get the information?

I seek for all primes wheater Top5000 or not!

I'm also aware of the test-server for n>50k for 1200<k<10000 and just testing all n<50k by myself!

Thanks a lot and I'm hoping to get more results for those Proth-list.

As for smaller primes in PRPNet, all you have to do is access the primes page of each port for a list of all the primes.

Most of the primes found in BOINC are listed in the Prime Pages. However, there were a few times where the leading edge of the search fell below the 5000th prime and thus was not reported.

Creating a public proth primes database has been a pipe dream for the past TWO years. Hopefully now with your help, it can become a reality. :)

I've uploaded a text-file with all PG primes found so far to http://www.rieselprime.de/dl/PG_Primes.txt (800 kB).

15556 primes including:

- all Top5000 primes upto 2010-10-16
- all primes from PG-Database like http://www.primegrid.com/primes/?section=decimal&primeid=1 up to id 13518
- all small primes from port 11000

Not yet included:
- primes from port 10000 (not available)
- some listed small primes in PRPnet-thread

Another reason for having primes from PRPNet (and elsewhere) in one place is to eliminate duplication. This week I've re-discovered prime on PG already found by someone else (outside PG).

Here's another example for the need of such Database I've just found:

The Top5000 Database from Mr. Caldwell contains a doubled entry, namely:

155*2^67973+1:
http://primes.utm.edu/primes/page.php?id=62875
http://primes.utm.edu/primes/page.php?id=8508

So it's undiscoverd for ten years now!?

I've mailed Mr.Caldwell.

By now all Top5000 links for k<1000 are now available at http://www.rieselprime.de/Data/P00001.htm.

Statistics for k<1200:

- 19375 primes listed
- 5535 Top5000 links

Next updates to come:
- all twins for k<1200 marked (perhaps today)
- all primes / Top5000 links for k<10000 ! (next week, hope so)
(When I'm ready with testing all 1200<k<10000 and n<50000; about 15% done)
- all PG PRPnet primes for n>50000 (as so far available/known) (next week)
- current reservations (next weeks)
- changing menu / adding stats to http://www.rieselprime.de for Proth-side (next week)

Karsten

Yep, I know that link already, thanks.
See link to text-file in this post.

Yes, I realized there're not only Proth primes in there, no problem.

And no, this 'Proth Database' does not mean automatically updating the PG prime finder stats.
This page(s) will only be a summary of all (sometimes) known Proth primes!

Karsten

Next updates to come:
- all twins for k<1200 marked (perhaps today)

Next update:

The summary page for Proth primes lists now:

- all known primes for k<10000 (115,224 so far)
-- including all Top5000 primes (18,200 links inserted)
-- including all PG primes (upto yesterday)
--- from PPSE 10000 server
--- some from these forum threads
--- some from older PPSE 10000 and 11000 server (most were lost)
- all known twins for k<10000 (2271 so far)

Notes:
- the search-range for k>1200 is set to n=50k although not all are done (hope next week)
- same for dates (set to 2010-01-10, will changed into last prime found later)
- for colors and definitons see here
- Nash weights were calculated with psieve3.exe
- Notes (see example for k=3, red star) could be inserted for factors of F / GFN

ToDo:
- current reservations (mostly for k<1200 from ProthSearch.net)
- splitting and inserting html-pages like for Riesel-primes

Please everyone who finds an error or missing prime, post here or PM me,
the more information I get the better that page(s) become.
If anybody got some old result-files, they're welcome, too.

Thanks.
Karsten

PS: Top5000 links for 1000<k<1200 not yet there. Coming next!

I've just uploaded the newest testpage for Proth primes.

New:
- creating reservations / ranges done from data file
(for now: if no reservation available:
k<1200: range done at 640k
k>1200: range done at 50k)
- all Proth primes from Top5000 Database

I'm also done 1/3 of the 1200<k<10000 and n<50000 tests (~90,000 primes found).

The newest attempt is to create a page of all persons who found any Proth prime ever from Top5000. This could be useful for PG's participants.
It should be doable including non-Top5000 primes, too.
But there's nothing to show yet.

Karsten

Update:

- newest primes (from 2 hours ago from PPSE10k and mine for n<50k) are online
- many reservations/ranges for k<1000 updated
- begun to include comments for primes (red star) like "Divides F(x) ... GF(x)
(so far only for k=3 and only info. from Top5000 Database
- display of ranges now with abbrev. "K" or "M"
- a bit less than 1/2 of range n<50k done

Stats:
- 5000 k-values (k=1-9999, more will come after splitting page)
- 122789 primes
- 19396 Top5000 links
- 2271 twins

Next works:
- getting more info for F/GF-factors
- more reservations
- creating user-primes-page
- updating Top5000 primes for last 2 weeks

Future:
- creating page with stats
- creating page with all reservations from prothsearch.com (like range-tables there)
- more k-values/primes for k>10000

____________
RieselPrime Database (... and now Proth Primes, too)

It's done!

The (almost) whole data for k<10000 are online.

I've created pages like for the Riesel-side, so for k<300, 300<k<2000, 2000<k<4000,...
New Menu set up including a small Statistics-page.

See here for more datails.

Just now NPLB is rallying, so the n<50k have to wait some days.

I'm trying to update every day all new primes from PG port 10000.

____________
RieselPrime Database (... and now Proth Primes, too)

Another update:

I've included Status pages for reservation / completion for 3 different k-ranges with corresponding n-ranges.
All data taken from W.Keller's page (prothbooks= like guestbook with reservations).
So far the timeframe from Feb.2008 to Nov.2010 is shown, more older will follow.

Holding the mouse over a contributor in the table will show 2 dates (if available):
- first date is reservation
- second date is completion
- some comments (red star) mostly for ranges

It's possible to inlcude the primes, too (as tooltip or comment) if needed.

The look and ranges may change, I'm still trying to find the best fit.


____________
RieselPrime Database (... and now Proth Primes, too)

It's done!

The range 1200<k<10000 and n<50000 I've completed:
104849 primes found and listed on my pages.

A few days and all primes for n<100000 are known with PPSE10k effort!


____________
RieselPrime Database (... and now Proth Primes, too)

Hi all,

after a long time now, trying to display Proth primes on my pages, too, it's still hard to find appropriate information here:

- Status of ranges tested by PrimeGrid are only available on the "Subproject status" link, but
- for a running range only lowest and highest testing n-value
- for finished ranges only highest n tested and number of primes found

- found primes only "listed" at Top5000 (if they are in) or
for example for PPSE from the user-status tables

Again my request:

It would be very nice and helpful to find a page like this on the Proth Search:

- giving all primes found and ranges tested by PrimeGrid.

There're many pages for user stats and badges and challenges but not such simple display of the results found here!

Please, make such overview.

Thanks
Karsten

RieselPrime Database (... and now Proth Primes, too)

Yes, I would also appreciate a page like that. It would be a nice contribution to human knowledge.

Thanks for the links again, I know them all.

But:

a) 2 servers for PPSElow -> 2 pages with (unsorted) primes, only listed by date
b) no page for found primes of n greater PPSElow-range -> get those only from Top5000
c) goals for 2012: one post (changing) with current information

Problems:

a) I have to download 2 pages and input them into a textporcessor to get those data I need

b) I have to download every new prime and input them into a textporcessor to get those data I need

c) I can't even use a textprocessing tool to get those information.

In short:
It's too much manually work to get all information to update my pages.

On the other hand I think it's a must have for a big project like PrimeGrid to show their results in a userfriendly manner but here is nothing since beginning... it's not the exercise of somebody like me.

So please, find somebody to create such pages, and for the other subprojects, too.

Thanks
