Miracles happen from time to time... and I discovered the second Fermat factor of this year, my very first on my birthday's week!
I started searching with Leonid Durman in the late 1990.
The factor has 30 digits, and was found using a Intel 9800x with a Nvidia RTX2060 and the program mmff from George Woltman.
Congratulations to FermatSearch, we now have 357 Fermat factors known!

Congratulations Luigi! And a Happy Birthday (best Birthday present ever!)

Congrats and Happy birthday. You just missed your BD present, I think now you need to learn your own address better!

(trivia: for who doesn't know, we sent Luigi a parcel to Italy, which is now on the way back to us in Thailand, because he gave us a wrong address and Italian post could not find him

. He had a whole adventure trying to get that parcel from the office, but at the end, it was futile, they could not figure out where the parcel is, and blamed the couriers. Morons!)

On the other hand, you just hit Serge so hard with your discovery, he's malding with envy, in spite of lifting that finger, look at his face!

New Fermat factor from Gostin and FermatSearch!
14698299 . 2²⁵⁶⁰²+1 is a Factor of F₂₅₅₉₉!!!
Gary Gostin discovered the third Fermat factor of this year!
This was discovered on an AMD EPYC 7702P based server running pmfs which incorporates George Woltman's gwnum library.
Congratulations to Gary from FermatSearch, for his 85th factor, we now have 358 Fermat factors known!

Congratulations, Luigi, this was a well-deserved discovery and the fourth smallest Fermat number with unknown character. I remember that you were also searching on F31 when you were scooped on that one, but you were such a good sport, remarking that it was great for the Fermat factor community that it was discovered.

Thank you Phil

It was so long ago, and still so clear in your mind!
Now I can say I did the right thing. Fermat rules!
