Calculating higher order terms for Electron Anomalous Magnetic Moment

[Adrian59]

TL;DR Summary

Does anyone know how to calculate the coefficients for higher order (sixth and beyond) terms for the electron anomalous magnetic moment?

Does anyone know how to calculate the coefficients for higher order (sixth and beyond) terms for the electron anomalous magnetic moment? I have a clear understanding of calculating the Schwinger term, but beyond that I cannot find anything in the usual QFT textbooks. The usual papers often quoted (eg Peterman, Levine, Kinoshita and Laporta) are short on detail. I know that the number of terms rises with the increasing order so that the higher order terms require computer algorithms to calculate these coefficients - often using Monte-Carlo integration methods, but these papers do not even show in broad terms how these calculations are phrased.
