I attemped to make a Platonic solid from cheese puffs. No, there was no real plan to this.

Plato made the solids, and five were gifted to the mathematicians. But in secret Plato forged a sixth solid to rule over all the others.

New nerd/geek diagnostic check. Ask them to identify this shape:
Tumblr media
If they say 'icosahedron', they're a nerd.
If they say 'd20', they're a geek.

Regular-ish Convex Polyhedra Bracket — Round 5 (Finals)
Tumblr media Tumblr media
Propaganda
Truncated Icosidodecahedron:
Also called the Rhombitruncated Icosidodecahedron, Great Rhombicosidodecahedron, Omnitruncated Dodecahedron, Omnituncated Icosahedron
Archimedean Solid
Semiregular
Dual of the Disdyakis Triacontahedron
It has 12 regular decagonal faces, 20 regular hexagonal faces, 30 square faces, 180 edges, and 120 vertices.
It has the most edges and vertices of all platonic and archimedean solids.
Of the vertex-transitive polyhedra, it fills up the most of the volume of the sphere it fits in (89.80%).
It is not actually the shape you get when you truncate an icosidodecahedron, although it is topologically equivalent.
It is the mod's favorite three-dimensional shape.
They made a void truncated icosidodecahedron and it's glorious. I had one for a while, it's hard to turn because of alignment issues, especially the decagonal sides. Fun puzzle tho, never did figure out how to permute the last layer...

once on this app i saw someone call kepler-poinsot polyhedra queerplatonic solids and that post occupies a significant amount of space in my brain. i think about it daily.

your pfp looks cool! is it some sort of 4d polytope?
Oh, cool, my first question!
My pfp is a projection of the 120 cell (4d equivalent of the dodecahedron) with 4 fibres of a hopf fibration highlighted, which is adjacency-equivalent to the (faces of the) dodecahedron
