I am working a problem from the Mohapatra textbook unification and supersymmetry and the question is to show that if any rep of a grp is pseudo real then it is automatically anomaly free. There is not much in the chapter (2) on how to go about this. All I know is that for a pseudo real group G = G* (the conjugate is the same as the original group). The group is not real though. I've been searching the web and books for a couple of hours now to no avail so thought I'd leave the question here.
