A Rhombicidodecahedron-Variant Which Features Octagons

This polyhedron contains the twenty triangles and twelve pentagons of a rhombicosidodecahedron — but they are all smaller than those found in that solid. As a result, the thirty squares of the rhombicosidodecahedron have each become, instead, irregular octagons.

The Dual of a Rhombicosidodecahedral Cluster of Rhombic Triacontahedra

The Dual of a Rhombicosidodecahedral Cluster of Rhombic Triacontahedra

Once I completed the polyhedral cluster seen in the last post, I became curious about its dual, which is what you see here. The overall shape here resembles an icosidodecahedron — the Archimedean solid which is, itself, the dual of the rhombic triacontahedron.

Rhombicosidodecahedral Cluster of Rhombic Triacontahedra

Since rhombic triacontahedra can form pentagonal rings, triangular rings, and square rings, I wanted to find out if a rhombicosidodecahedron could be built out of these building blocks. As you can see here, the attempt was a success. Each rhombic triacontahedron which appears here is located at the vertex of a rhombicosidodecahedron.

The 122 faces are twenty blue, irregular hexagons; thirty red, irregular hexagons; 60 rectangles, and twelve regular pentagons.

A Polyhedron Featuring Kites and Regular Dodecagons

A Polyhedron Featuring Kites and Regular Dodecagons

The dodecagons are in the same planes as a cube’s faces, so there are six of them. Also, this could be constructed via an unusual truncation of the cube, using three different truncation-planes at each vertex. This polyhedron has thirty faces: the six dodecagons, and twenty-four kites (in eight sets of three).

A Big Ball of Pyramids

A Big Ball of Pyramids

To create this, a central rhombicosidodecahedron had each of its faces augmented by pyramids, each of which uses only equilateral triangles for lateral faces.

The 152 faces of this polyhedron are:

    • 12 regular pentagons
    • 60 trapezoids
    • 20 small, equilateral triangles
    • 60 large, slightly-isosceles triangles
