Yes and so it should be. It is an ECPP proven prime big enough to get into the top20. Marcel Martin's Primo does not have a monopoly on such proofs. Wise up,

Congrats to Facq, Asuncion and Allombert for breaking the ECPP 30k barrier with the proof of U(148091) -- Fibonacci Number with 30,949 decimal digits.

looks like no one claimed it, and i've de-crufted my machine and set up, so i'm working on this candidate again!!

I should be continuing these shortly into the new year

I can do the Mersenne cofactor Ryan reserved about a year ago too. Ryan?

Hello Paul, what is the status of your ECPP-Repunit number ?

It is imminent. A week or so.

Do you mean R(49081)? Or generalized repunit primes in bases other than 10?

I didn't know PARI supported ECPP certificates out of the box. Does anyone know how fast it is compared to Primo? And how to make it run multithreaded?

It would be very nice to have an efficient ECPP method that runs in terminal mode.

Btw, I wanted to test it with a random 300 digits PRP from factordb but the certificate isn't accepted: "No input number found in file." I attached the cert, it seems to contain the input number.


(and sorry for sort of hijacking the thread, I didn't want to open a new one just for this, but if desired I can surely do so)
