Gigantic Probable Prime Triplet found - Page 2

Thanks for the info, version 3.0.3 was limited to 10000 bits, but I did not realize that the restriction had been lifted in version 3.0.6. I will be curious to try it.

That is not a problem. Marcel Martin tell me the solution.

Extented the PRIMO.ini file with lines:

"
[Setup+]
MBS=40000 <- maximum bits accept

"

AFAIK, Primo 2.3.3beta had much more discriminant tables than 3.0.6 has. There were eight files primo.xd1, primo.xd2, ..., primo.xd8 (taking over 7 Mb) in 2.3.3beta, while there are only five files primo.xd1, primo.xd2, ..., primo.xd5 (just over 3 Mb) in 3.0.6.

Am I wrong?

I just noticed that F. Morain proved the primality of the "+5" number and that your triplet is now on Top-5000 listed as the new record.

Congratulations!

Any hints on how FastECPP performs against Primo?

Hello ET,

I reckon , at FASTECPP works many PCs for one downrun ( In PRIMO is it "TEST" ).

In PRIMO , you can with a trick also finished a TEST with several tasks.

So I had have the certificate of a 6k number in 800h.

I see you followed up with a record quadruplet. Congrats!
