Query: E6Tensors: A Mathematica Package for E6 Tensors   We present the Mathematica package E6Tensors, a tool for explicit tensor
calculations in E6 gauge theories. In addition to matrix expressions for the
group generators of E6, 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.
