The M130439 cofactor seems stuck. I am releasing it.[/QUOTE]


Thank you Paul ! :tu::fusion:

Can someone please update [url]https://en.wikipedia.org/wiki/Elliptic_curve_primality#Elliptic_curve_primality_proving[/url] with Andreas Enge's [URL="https://primes.utm.edu/primes/page.php?id=134003"]10^50000+65859[/URL] certification. My IP address is blocked from doing so.

It seems like somebody did that already.

Ramanujantau in PrimePages
 
Hello,


I have certified ramanujantau(47^4176) and try to submit it to the PrimePages. Does anyone know how to code it? I tried the html format indicated by [URL]https://primes.utm.edu/primes/page.php?id=120374[/URL], and also "tau (47^4176)" and "ramanujantau(47^4176)", but none of them worked.

It's a bit involved. I think you have enter the whole number as a "blob" and give it the label: "tau(47^4176)". However if it does not have more than 26,709 digits as of today it is inadmissible to the [URL="https://primes.utm.edu/top20/page.php?id=27"]top20 ECPP proofs[/URL].

It's comfortably above that. [url]http://factordb.com/index.php?id=1100000003605931235[/url]

But it's quite remarkable how quickly that lower limit is rising since Andreas released this new ECPP implementation!

Thanks for the explanation! Indeed it can be entered on the second submission page [URL]https://primes.utm.edu/primes/submit_full.php[/URL]. Adding the ECPP comment was not straightforward, I hope I did it correctly - it appears on its own page [URL]https://primes.utm.edu/primes/page.php?id=134074[/URL] now, but not (yet?) in the list of 20 largest ECPP primes.

The database re-ranks primes every 30 mins.

It is ranked now. Try adding a comment.

The [URL="https://primes.utm.edu/top20/page.php?id=23"]top Generalized Lucas Number[/URL] is U(24, - 25, 43201), which is equal to (25^43201+1)/26, but it is still "PRP" in [URL="http://factordb.com/index.php?id=1100000000434269528"]factordb[/URL] and no Primo certificate in factordb, and [URL="https://primes.utm.edu/primes/page.php?id=130933"]its top5000 page[/URL] says "CHG with N-1 factored part 27.39% with p8022, p1749 and p849 proven with Primo", so can someone update its primality certificate to factordb?

AFAIK factorDB lacks the ability to verify both KP and CHG proofs.
