DESCRIPTION:Abstract:Multi-Higgs-doublet models equipped with global symme
 try groups\, either exact or softly broken\, offer a rich framework for co
 nstructions beyond the Standard Model and lead to remarkable phenomenologi
 cal consequences. Knowing all the symmetry options within each class of mo
 dels can guide its phenomenological exploration\, as confirmed by the vast
  literature on the two- and three-Higgs-doublet models. Here\, we begin a 
 systematic study of finite non-Abelian symmetry groups which can be impose
 d on the scalar sector of the four-Higgs-doublet model (4HDM) without lead
 ing to accidental symmetries. In this work\, we derive the full list of su
 ch non-Abelian groups available in the 4HDM that can be constructed as ext
 ensions of cyclic groups by their automorphism groups. This list is remark
 ably restricted but it contains cases which have not been previously studi
 ed. Since the methods we develop may prove useful for other classes of mod
 els\, we present them in a pedagogical manner.
