Here you can download the Mathematica files used for the calculations of paper 18A2 Renorm, where the notation is explained. The files also contain the results. The calcutations concern the absorptive part of the graviton self-energy and the one-loop renormalization of the strictly renormalizable theory of quantum gravity formulated in paper 17A3 Renorm
Clicking this link you are sent to the files that contain the beta functions of the simplest model of superrenormalizable quantum gravity studied in paper 17A3 Renorm
