Is Bern(8286) now proven ?

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

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.

Here are maybe more Primo jobs ?!

Even I found the smallest 20000 digit twin PRPs.

10^19999+1514722609+d,d=0,2

Smallest 20000-digit PRP is 10^19999+110949 / found by Patrick De Geest

best,
Norman

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

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

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