Bases 2 & 4 reservations/statuses/primes

[mdettweiler]

Gary, could you possibly add a link to Jean's page for sieved files for these and the base 4 conjectures at http://jpenne.free.fr/ConjRus/ to the respective Conjectures 'R Us web pages, like you do for directly posted sieve files? Something like "Sieved files available at ..." would do the trick. Right now it's somewhat of a hunt to find the web address to get the sieved files.

Excellent idea. I'll do that with my next page updates.

even Riesel:

k=175567 at 815k
k=239107 at 1040k (don't know where the last value at n=1.103M i gave came from!)

That's k=351134 and 478214 for conjecture purposes, which is the way I have to show them on the pages and so the way I'd prefer they be stated here.

For k=478214, since there's been no (or negative!) progress since Sept. 9th, 2008, I'm leaving the status date unchanged.

Will you be working on these in the near future?

k=351134 at n=847k

will continue up to the testlimit of k=478214 and then test both together!

Hi,
I extended the Riesel presieved files to n = 16M base two.
Now, both Sierpinski and Riesel active files have exponents up to 16M base two.
Please, see http://jpenne.free.fr/ConjRus/ for details...

For now, Riesel files are sieved up to 10.43 Tera,
and Sierpinski files are sieved up to 16.34 Tera.

(I am now using sr2sieve which is much faster than srsieve)

I hope to reach the 20 Tera in Dec. 2009 for Sierpinski and in Feb. 2010 for Riesel.

Riesel even n's :
My status for k = 9519 is to-day n = 1,568,160 no prime...

Regards,
Jean

Hi,

I observed that the links to Liskovets-Gallot page that are in the
http://www.noprimeleftbehind.net/crus/ site pages are no more valid.

The correct URL is : http://www.rieselprime.de/Related/LiskovetsGallot.htm

More generally, The URL for the "Riesel Prime Database" site is : http://www.rieselprime.de/

The old address : http://www.rieselprime.org/ is no more valid!

Regards,
Jean

Oh! Thanks for pointing that out. I had corrected all of those at NPLB but forgot I had references to them in the CRUS pages. I'll correct them shortly.

Riesel odd n's

I'll going to start working on k=155877 starting at n=1049525 base 2

[MyDogBuster]

Sierpinski odd n's

I'll going to start working on k=85287 starting at n=1065947 base 2

Hi,

Now, Riesel files are sieved up to 15.06 Tera,
and Sierpinski files are sieved up to 20.00 Tera.

(I am now using sr2sieve which is much faster than srsieve)

Note that, now, the two remaining k's for Sierpinski even n's (23451 and 60849) are deeply sieved, and so, may be LLR tested for n's above 2M!
Same remark, for Sierpinski odd n's, k = 32247 (64494) and k = 9267 (18534).

Riesel even n's :
My status for k = 9519 is to-day n = 1,623,616 no prime...

Jean
