Star Polyhedron

DOWNLOAD Mathematica NotebookDownload Wolfram Notebook

A star polyhedron is a nonconvex polyhedron which contains an arrangement of symmetrically (nor nearly symmetrically) arranged spikes giving it the visual appearance of a three-dimensional star. Star polyhedra can be constructed from concave polyhedra via stellation or augmentation.

Examples include the stella octangula and Kepler-Poinsot polyhedra.

Star polyhedra appear prominently in the architecture of European churches (Tarnai et al. 2007, 2008).
