Great stellapentakis dodecahedron
Introduction 3D model of a great stellapentakis dodecahedronIn 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.
Proportions The triangles have one angle of  and two of . The dihedral angle equals . Part of each triangle lies within the solid, hence is invisible in solid models.
