| Summary:

In this note, we give a definitive basis for the dimension-eight operators
leading to quartic — but no cubic — interactions among electroweak gauge
bosons. These are often called anomalous quartic gauge couplings, or aQGCs. We
distinguish in particular the CP-even ones from their CP-odd counterparts.
