Numerical work with sagemath 3 – tetrahedron graphs

A spin network is a directed graph whose edges are associated with irreducible representations of a compact Lie group and whose vertices are associated with intertwiners of the representations adjacent to it. I have been exploring some of the techniques of graph theory in the context of tetrahedron graphs.
