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.
The triangles have two acute angles of
The dihedral angle equals
Part of each triangle lies within the solid, hence is invisible in solid models.
