Query: Classifying Accidental Symmetries in Multi-Higgs Doublet Models   The potential of $n$-Higgs Doublet Models ($n$HDMs) contains a large number
of SU(2)$_L$-preserving accidental symmetries as subgroups of the symplectic
group Sp(2$n)$. To classify these, we introduce prime invariants and
irreducible representations in bilinear field space that enable us to
explicitly construct accidentally symmetric $n$HDM potentials. We showcase the
classifications of symmetries and present the relationship among the
theoretical parameters of the scalar potential for; (i) the Two Higgs Doublet
Model (2HDM) and (ii) the Three Higgs Doublet Model (3HDM). We recover the
maximum number of $13$ accidental symmetries for the 2HDM potential and for the
first time, we present the complete list of $40$ accidental symmetries for the
3HDM potential.
