The bug has been reported at:
I thought it was fixed in FeynCalc 6.0, but I try the following code:
R=Tr[GAD[a, b, c, d, 5, e, f]] // Simplify
GAD[a, b, c, d, 5, e, f] // DiracSimplify
Tr[%] // Simplify
R - % // Simplify (*non-zero*)
Tr[GAD[e, f, a, b, c, d, 5]] // Simplify
R - % // Simplify (*zero*)
it seems that the bug is not fixed in FeynCalc 6.0, can anyone confirm this?
Thanks a lot.
