 I’ve stumbled upon a frustrating bug in the FeynCalcExternal form of
D-dimensional Eps expressions. Essentially, the expressions behave
differently depending on how many of their indices are contracted with
four vectors (and which indices are contracted!).
 Attached is a short notebook file that illustrates the point
concisely. Has anyone else run into this?

 Thanks,
