Classical Compound of Five Tetrahedra

picture

This is a the well known compound of 5 tetrahedra that has all the rotational symmetries of a dodecahedron. This polyhedron is also a a stellation of the icosahedron. In "The Fifty-Nine Icosahedra" by Coxeter e.a. it is mentioned as the 46th stellation or by cell names "E f1".

I built a model of this one somewhere in the 80s after visiting Science Museum in London. I bought a book with a ready template and I remember that I thought it was very hard. It must have been one of the first polyhedra that I built. I am not sure what happened with the model. I must have thrown it when I moved to Sweden.

I decided to make a new model using the same material and colours as for the other compound of tetrahedra that I built. The model only consists of 60 facelets, the minimum for a polyhedron with 60 symmetries, but it is still a model that requires some planning and patience. This is quite common for a model without reflections. This model was built in Januari 2024.
