Mathematical Model – Great Icosahedron
A mathematical model of a great icosahedron. The model is constructed from a stiff, glossy cardboard-like material.
Mathematical Model – Cubohemioctahedron
A mathematical model of a Cubohemioctahedron. The model is constructed from orange and yellow cardboard.
Mathematical Model – Truncated Octohedron
A mathematical model of a truncated octohedron. The model is constructed from blue and orange cardboard.
Mathematical Model – Rhombic Dodecahedron
A paper model of a rhombic dodecahedron. The model is constructed from pale green, pink, orange/ brown, and white folded papers. The papers are printed in Japanese and Roman lettering.
Mathematical Model – Stellated Truncaded Hexahedron
A cardboard model depicting a stellated truncaded hexahedron. Some surfaces are coloured in blue, pink, green, and yellow. The remainder of the model is beige. The cardboard has a subtle texture.
Mathematical Model – Four Congruent Orthschemes
A wooden model depicting four congruent orthschemes. The model is in four identical parts. The wood is varnished.
Mathematical Model – Cube
A small paper model of a cube. The model is constructed of blue, green, and pink folded papers.
Mathematical Model – Snub Cube
A paper mathematical model depicting a snub cube. Square faces are in light blue, triangular faces are in yellow.
Mathematical Model – Snub Dodecahedron
A paper model of a snub dodecahedron. The hexagonal faces are in light blue, triangular faces are in pink.
Mathematical Model – Compound of 5 Octahedra
A cardboard model depicting a compound of five octahedra. The model is coloured in blue, green, yellow/ orange, and orange. A small metal ring permits the model to be hung. The display at the Department of Mathematics describes this model as follows: “â€świth the face-planes of an icosahedron, each used
