Add symmetries of Passarino Veltman coefficient functions #121

Closed vsht closed 2 years ago

vsht commented 3 years ago

It is rather trivial to enumerate these symmetries for given ranks and to generalize that to arbitrary ranks, cf.

One just has to think how to implement it in such a way, that it can be used to simplify relations involving multiple PaVe functions.
