Hallo,

I noted a problem with renaming variables and the application of
DiracOrder:

I have added a small sample notebook which illustrates this problem:
when I write a sum of \gammas in different ways and order them, I get a
difference if I make a renaming of momenta before or after the
“DiracOrder”.

Please, look at the appended notebook: Bug_in_FC.nb
