Truncated dodecahedron
Tumblr media
By cutting off the vertices of the dodecahedron you get the truncated dodecahedron.
Tumblr media
This results in the 12 pentagonal faces of the dodecahedron turning into 12 dekagonal (10-gonal) and 20 triangular faces.
(As the dodecahedron has 20 vertices, truncation results in 20 triangular faces.)

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

Some people have even said they're knitting apparatuses (apparati?) to make cords of knitting. These things are wonderfully weird and mysterious.

Hey, if bill were a dodecahedron, what would he look like?
Tumblr media
Hmm idk but this is my interpretation of him if he was one! The flower is an unfolded dodecahedron and he’d definitely look like this to play dungeons and dragons with ford :>

Polyhedra on dotted isometric paper
Tumblr media Tumblr media Tumblr media Tumblr media
Tumblr media
Drawing polyhedra on dotted isometric paper is so calming. One does not need to use a ruler or a compass. Instead one can just count dots to determine the length, and play around with the angles.

My infinity dodecahedron in the image of an exotic engram from Destiny 2.
Tumblr media
When turned off it's a solid silver surface, but turned on it shows the inside.
Tumblr media
It's also animated with several color options

Truncated Cuboctahedron:
Also called the Great Rhombicuboctahedron
Archimedean Solid
Semiregular
Dual of the Disdyakis Dodecahedron
It has 6 regular octagonal faces, 8 regular hexagonal faces, 12 square faces, 72 edges, and 48 vertices.
Not actually the truncation of the cuboctahedron, although topologically equivalent.

Although it's a month late, I'd like to wish everyone a happy new year! May 2024 be full of mathematics. So yeah, here's why 2024 is a dodecahedral and tetrahedral number.
