Great stellapentakis dodecahedron

In geometry, the great stellapentakis dodecahedron (or great astropentakis dodecahedron) is a nonconvex isohedral polyhedron.

It is the dual of the truncated great icosahedron.

It has 60 intersecting triangular faces.

The triangles have one angle of

The dihedral angle equals

Part of each triangle lies within the solid, hence is invisible in solid models.
