**Vertex description:**5/2.3.5/2.3**Faces:**32**Edges:**60**Vertices:**30**External facelets:**132**Dual:**Great rhombic triacontahedronThis uniform polyhedron's faces consist of 20 triangles and 12 pentagrams. Can you spot them?

The polyhedron can be thought of as a half-way point between the great stellated dodecahedron and its dual the great icosahedron. It's relationship to those regular polyhedra is the same as the icosidodecahedron's relationship to the dodecahedron and its dual the icosahedron. In both cases the uniform polyhedron can be found at the half-way point when

*morphing by truncation*in Small Stella, Great Stella, or Stella4D.This is one of my favourite polyhedra!

You can see roughly how big the model is here. Here is a very small version of the model made using SLA rapid prototyping, along with a model of its dual.
