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! edit: downside of having multiple, random avatars, haha Last fiddled with by LaurV on 20210302 at 06:55

New Fermat factor from Gostin and FermatSearch! 14698299 . 2^{25602}+1 is a Factor of F_{25599}!!! Gary Gostin discovered the third Fermat factor of this year!

Congratulations, Luigi, this was a welldeserved 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.

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