Is Bern(8286) now proven ?


I asked, maybe we should set lower parameters (dd=3000,not dd=11000) and get another way earlier...

10000 digit twins
 
So folk, the certifications are done and uploaded to factordb.com

10^9999+2421018649+d,d=0,2 are the smallest gigantic PROVEN twin primes.
Maybe it should be mention in wikipedia ?!

Numbers was found first by Dirk Augustin in 2010 and now proven primes by Norman Luhn.

:thumbs-up:

These are not "top20" special forms at the PrimePages. They would take you 16 times as long each as the 10k digit primes you certified.

I know this, but it is maybe for a TR "a quick bit" between breakfast and lunch:grin:


This twin is just listed as PRP in my project file.

[QUOTE=Gelly;576620]Done! 6693424s (77.5 days). I'll first be tinkering with the cofactor of Bern(8286) (hopefully a month-ish at most), but after seeing Paul go hogwild on reservations, my next reservation is PRP32010, or M106391/286105171290931103.[/QUOTE]

i relinquish my reservation for the time being. do feel free to claim it, as my machine is problematic as of late.

Facq, Asuncion & Allombert are now exercising an alternative ECPP implementation with Pari/MPI.

Why (2^95369+1)/3 is not shown in [URL="http://www.ellipsa.eu/public/primo/top20.html"]http://www.ellipsa.eu/public/primo/top20.html[/URL]? It has been proven to be prime, see [URL="https://primes.utm.edu/top20/page.php?id=67"]https://primes.utm.edu/top20/page.php?id=67[/URL]
