In my last post I indicated how far I had got in porting the code for the monochromatic 4-valent node from Mathematica to sagemath. This is essentially complete now and I have just got to output a graph of eigenvalues of curvature versus spin.
As yet the code is unoptimised. Below is a sample of the output so far:
So now the eigenvalues have been found I can start to make use of them in calculations of the Hamiltonian Constraint Operator.
