I will present a systematic field theory prescription for constructing 3D N=4 mirror pairs involving quiver gauge theories beyond the well-known ADE examples. The construction involves a certain generalization of the S operation, which arises in the context of the 3d SL(2,Z) action on a CFT with a U(1) 0-form symmetry. I will show how this construction can be used to determine 3d Lagrangians for a large class of Argyres-Douglas theories compactified on a circle. I will also discuss how the prescription can be extended to include half-BPS line defects and determine the associated mirror maps, which were only known earlier for A-type theories.
