Hi,
I’m using FeynCalc 4.1.1 in Mathematica 4.2 for Linux, looking the
following it seems to be a problem evaluating Tr with GA[5]:

p=GA[b,c,d,e,f,5,a]//Tr//Simplify;
q=GA[c,d,e,f,5,a,b]//Tr//Simplify;
p-q//Calc//Simplify

gives non zero result

(-8*I)*(Eps[LorentzIndex[csi], LorentzIndex[rho],…] + Eps[…] + …)

Could you please give a look?
Thanks in advance.
Best Regards,
Francesco
