The polyhedron is a compound of five tetrahedra — it can be represented as a single body combining five multi-colored tetrahedra.
The performed coloring makes it possible to clearly separate the element of each of the tetrahedra participating in the merging process.
Another name for a polyhedron is the second compound stellation of icosahedron.
The face of the polyhedron are the three polygons highlighted in yellow in the figure.
A polyhedron consists of 20 groups of such polygons.
