# Great Stellated Dodecahedron

The shape is essentially an icosahedron with a three-sided pointy pyramid on top of each face. There are 10 groups each consisting of 5 triangles which are coplanar.

Mathematically however, it is actually composed of twelve intersecting pentagrammic faces. At each *outer vertex* three faces meet. The *inner vertices* are not true vertices at all in the sense that they are points where edges end and meet.
