We analyse the Higgs branch of 4d N=2 SQCD gauge theories with non-connected gauge groups SU(N)=SU(N)⋊I,IIZ2 whose study was initiated in arXiv:1804.01108. We derive the Hasse diagrams corresponding to the Higgs mechanism using adapted characters for representations of non-connected groups. We propose 3d N=4 magnetic quivers for the Higgs branches in the type I discrete gauging case, in the form of recently introduced wreathed quivers, and provide extensive checks by means of Coulomb branch Hilbert series computations.
