Small stellapentakis dodecahedron

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.

gollark: I'm going to spend much more time doing ground-level travel and being stuck in traffic queues and whatever than I am thinking about the aesthetics of it by satellite.
gollark: Like arguably most UK ones?
gollark: I would MUCH prefer that to an "interesting" and impossible to navigate city.
gollark: I'm also implementing the miller-rabin test because reasons.
gollark: Involving "elliptic curves" and "quadratic field sieves".
