Abstract We present the Mathematica package E6Tensors , a tool for explicit tensor calculations in E 6 gauge theories. In addition to matrix expressions for the group generators of E 6 , it provides structure constants, various higher rank tensors and expressions for the representations 27 , 78 , 351 and 351 ′ . This paper comes along with a short manual including physically relevant examples. I further give a complete list of gauge invariant, renormalisable terms for superpotentials and Lagrangians.
