snub dodecahedron

plural snub dodecahedra · plural snub dodecahedrons

1. geometryA polyhedron that has 12 pentagonal and 80 triangular faces and is an Archimedean solid.

   The form can be derived by triangulating the pentagonal faces of the snub dodecahedron (Fig. 19).

   This gives two points, A’, A₁’, which are projections of vertices of the two enantiomorphous snub dodecahedra that can be inscribed in the regular dodecahedron.

   The snub dodecahedron has 60 vertices, 150 edges and 92 faces of which 12 are pentagonal and 80 triangular. This polyhedron has I symmetry and can therefore be constructed in left- and right-handed forms.

   The result is a structure of two nested snub cubes rotated by an angle of 45° against each other (n = 24) and two nested snub dodecahedra, where the rotation angle amounts to 36° (n = 60).
