Hello Sir

I am a physical student , I have a problem with the LeviCivita

tensor when I try the following commands :

===

Tr[GS[p].GA[mu].GA[nu].GA[rou].GA[5]]

===

and it gave me a result with the letter p in the epsilon’s index position

Is it a bug ? and How can get the correct form

Thank You very much
