While considerable progress has been made in classifying realisable symmetry groups in three-Higgs-doublet models\, the completenes s of existing classifications remains an open question. In this talk\, I r evisit conventional symmetry transformations from a new perspective\, lead ing to a more systematic framework for identifying realisable symmetries. I then extend the analysis to the recently proposed GOOFy transformations\ , which act non-trivially on scalar doublets and their conjugates.
