Regular-ish Convex Polyhedra Bracket — Round 5 (Finals)

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...

Platonic Solid

Regular

Dual of the Regular Dodecahedron

It has 20 regular triangular faces, 30 edges, and 12 vertices.

You can insert an icosahedron inside an octahedron.

If the edge length of the octahedron ist 1 + Phi (1.618), the egde length of the icosahedron is SQRT(2).

A friend showed me this picture by Casey house:

[Source: Caseys website ]

And I had to draw it in isometric projection.

Very neat.

One could also make that even further and put an octahedron into the icosahedron and so on...

Two more planar graphs of an icosahedron. Well, left one is missing three edges, actually.

In this perspective the icosahedron drawing fits neatly into this hexagon shape.

Regular-ish Convex Polyhedra Bracket — Round 2

Propaganda

Disdyakis Triacontahedron:

Also called the Hexakis Icosahedron, Decakis Dodecahedron, Kisrhombic Triacontahedron

Catalan Solid

Dual of the Truncated Icosidodecahedron

It has 120 scalene triangular faces, 180 edges, and 62 vertices of three types.

It is the face-transitive convex polyhedron with the most faces, thus makes the highest fair die (120 sides).

Polyhedra on dotted isometric paper

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.
