An icosidodecahedron


icosidodecahedron (plural icosidodecahedra or icosidodecahedrons)

  1. An Archimedean solid with thirty-two regular faces (twelve pentagons and twenty triangles).

      [] together to form not only regular polyhedrons but rhombicosidodecahedrons, truncated icosidodecahedrons, and such.

      A succession of 10 concentric icosidodecahedra centered at (0, 0, 0), forming a geometric sequence (the nth one is τn larger than the first one), is also put into evidence.
    • 2004, David Darling, The Universal Book of Mathematics: From Abracadabra to Zeno's Paradoxes[1], page 263:
      The edges of the octahedron form three squares; the edges of the cuboctahedron form four hexagons, and the edges of the icosidodecahedron form six decagons.

      Thus, there is a star octahedron, three star dodecahedrons, and fifty-nine star icosidodecahedrons.

      The dark-gray (online: red) icosahedra are part of the B clusters, the light-gray dodecahedra of the B’ clusters, and the (online: blue) icosidodecahedra of the M clusters.

      Polyhedrons include prisms; pyramids; the Platonic solids, including tetrahedrons, cubes, octahedrons, dodecahedrons, and icosahedrons; the Archimedean solids, such as cuboctahedrons and icosidodecahedrons; and the Johnson solids, such as square pyramids and triangular cupolas (dome-shape).
