Medial disdyakis triacontahedron


In geometry, the medial disdyakis triacontahedron is a nonconvex isohedral polyhedron. It is the dual of the uniform truncated dodecadodecahedron. It has 120 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.
