Gigantic Probable Prime Triplet found
 

Good news!

I found this week a Gigantic Probable Prime Triplet !
With huge efforts I found after 176 Gigantic Twins a set of
3 primes. Every prime have 10047 digits.

These are [B]2072644824759 * 2^33333 [/B]-1, +1,+5.

The problem, certify the 3rd number :-(

best wishes

Congratulations!

As for 2072644824759*2^33333+5,
you can try to contact [URL="http://primes.utm.edu/bios/code.php?code=M"]F. Morain[/URL] and ask him to prove it for you. He did such things in the past. A 10,000 digit proof is doable, he already proved 12k, 15k, and 20k numbers.

Thank you, but I have contact him ... he help me later. I had started PRIMO
v 3.06 but the number is to hard. No jump to TEST 2.

The 2nd chance is PRIMO v 2.2.0 beta 4. , perhaps he found a way.

PRIMO v. 2204 don't start a downrun sequenz :-(...so I hope I get help from F. Morain .

where can u download the old version of primo

How many months would a certification take on a fast P4?

[quote=henryzz;145831]where can u download the old version of primo[/quote]

I have archived 6 versions , 2.0 , 2.204 , 2.205, 2.207, 301 and 3,06 .
You can't download no previous version.

I don't no. A P4 is slower than AMD Athlon / Phenom CPU.

But it exist a good estimate for running time.

Calculate ( (actual bits / total bits )^4.86) and you get the left running time in percent, independently from PC-System.

You get 60 months on a P4 3.2 GHz for a 10k number.

I used version 2.3.2 on a 16390 bit number - I wonder if it would exhibit any improvements over the versions you have listed. pm me if you want to try it.

Damn, you're right.

It possible I have also v 2.3.2, but 3.06 is faster or better for larger numbers.

It's no problem to get the other versions from me. Email me :-)

I had veriyfed a 6223 digit number ( the actual triplet record ) in record time with version 3.0. Only 800h I need with 4 simultanious tasks.
So it's possible to verify a 16390bit number in a week !

Also you can switched from v 2.3.2 to v.306 , it's easy !
