Augmented dodecahedron (isohedral deltahedron)

The augmented dodecahedron is an isohedral deltahedron. It can be formed by augmenting every face of the regular dodecahedron with a pentagonal pyramid. It is also a non-convex variant of the pentakis dodecahedron.

An interesting property of this polyhedron is that its convex hull is the exact uniform dual triakis icosahedron.
