Abstract
We present a complete and non-redundant basis of effective operators for the Standard Model Effective Field Theory up to mass dimension 12 with three generations of fermions. We also include operators coupling to gravity via the Weyl tensor. The results are obtained by implementing the algorithm of Li et al., and provided in the form of ancillary files.
