Great disdyakis dodecahedron
Introduction 3D model of a great disdyakis dodecahedronIn geometry, the '''great disdyakis dodecahedron''' is a nonconvex isohedral polyhedron. It is the dual of the uniform great truncated cuboctahedron. It has 48 triangular faces.
Proportions The triangles have one angle of , one of  and one of . The dihedral angle equals . Part of each triangle lies within the solid, hence is invisible in solid models.
Related polyhedra The ''great disdyakis dodecahedron'' is topologically identical to the convex Catalan solid, disdyakis dodecahedron, which is dual to the truncated cuboctahedron. :160px
