Small stellapentakis dodecahedron
Introduction In geometry, the '''small stellapentakis dodecahedron''' is a nonconvex isohedral polyhedron. It is the dual of the truncated great dodecahedron. It has 60 intersecting triangular faces.
Proportions The triangles have two acute angles of  and one obtuse angle  of . The dihedral angle equals . Part of each triangle lies within the solid, hence is invisible in solid models.
