In 4-dimensional geometry, the cuboctahedral pyramid is bounded by one cuboctahedron on the base, 6 square pyramid, and 8 triangular pyramid cells which meet at the apex. It has 38 faces: 32 triangles and 6 squares. It has 32 edges, and 13 vertices. Since a cuboctahedron's circumradius is equal to its edge length, the triangles must be taller than equilateral to create a positive height. The dual to the cuboctahedral pyramid is a rhombic dodecahedral pyramid, seen as a rhombic dodecahedral base, and 12 rhombic pyramids meeting at an apex. (Wikipedia).

Henry Segerman - Geared Mechanisms - G4G14 Apr 2022
We will present various 3D printed geared mechanisms. Two of these are octahedral and cuboctahedral variants of Buckminster Fuller's Jitterbug mechanism. Here the gears help stabilize the mechanism and prevent jamming. In the cuboctahedral case, the added gears rotate non-linearly, so requ

How to Construct a Dodecahedron
How the greeks constructed the Dodecahedron. Euclids Elements Book 13, Proposition 17. In geometry, a dodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid. A regular dode

Geared Cuboctahedral Jitterbug
3d print available at http://shpws.me/R8NY. This variant jitterbug mechanism is based on the cuboctahedron, expanding to become a rhombicuboctahedron. For this mechanism the rotation rates of the triangular and square parts are not linearly related to each other. This means that our gear
