50 vertices arranged in D6 symmetry is interesting in that it forms two different but close in length triangle strips -- one following the longitudes and the other the latitudes.

#Processing #glsl #shadersTetrahedral symmetry requires that a general point be in a set of 12 -- on each of the 4 faces in each of 3 orientations. You can also add 4 points at the vertices, 4 at each face center, or 6 at each edge center. Combined, any even number of points >= 4 can be arranged with tetrahedral symmetry, albeit not always evenly.
Here is 50 points in tetrahedral symmetry which requires that some of them have valence 7.

We can also get 80-vertex tetrahedral symmetry with a more "traditional" arrangement of 12 pentagons and the rest hexagons.

I particularly like this 104-vertex spherical tessellation with its nearly octahedral symmetry and 18 interwoven triangle strips.

Stammerda de wok cerca de dividerci ma noi rivendichiamo la nostra curtura condivisa co gli USA
Na curtura inizziata co Cristoforo Colombo, proseguita civilizzando 50 mijoni de nativi a corpi d'ascia e dando un lavoro a 12 mijoni de negri ne i canpi de cotone, e che cià regalato un paese cristiano che oggi culmina co la presidenza Trunp 👑
Lunga vita a gli USA! Lunga vita a Donard! E ricordate de gli amici 🙏

Qualcuno si ricorda un periodo confuso nei 2000 in cui c'erano dei modem (credo? forse schede grafiche?) con la scatola disegnata da Milo Manara?
Sono sicurissimo sia esistito, ma non riesco a trovarne prove online.

@GustavinoBevilacqua non nascondo che uso (altre) ai per ricerche rapide, ma niente “dialoghi”.
Poi ci sarebbe da discutere sui consumi energetici di una ricerca ai e ore passate sul webete a ricercare lo stesso… [magari questo lo scopriremo nelle prossime puntate…]

Si, la sua, la mia, ma dai tutto sommato anche cubalibre la possiamo considerare quasi monoutente.
Quella e' una maledetta cache, sono sicuro.
Se fai sparire la chiave del dominio fedi.vituperio.eu , semplicemente la prossima volta che gli serve, se la riscarica e la mette li.Tipo quando un server cambia indirizzo ip e hai una chiave sbagliata su known_hosts, togli l'offending keys e prosegui

tra l'altro mi viene in mente un problema, perchè...uhm...credo che Lorenzo abbia fatto tutto su un'istanza monoutente?
Cosa succede se ci sono utenti su questa istanza che ti stanno ancora seguendo sul dominio vecchio perchè magari non entrano da una vita e gli tolgo il dominio sotto al fondoschiena?
Uhmmmm.....
