Magnetic quivers for rank 2 theories

In this note we construct magnetic quivers for the known rank-2 four dimensional $\mathcal{N}=2$ superconformal field theories. For every rank-1 theory one can find a unitary quiver; observe that is no longer possible at rank 2. Our list of necessarily includes orthosymplectic quivers, in addition to ones, both simply and non-simply laced variety. Using quiver subtraction, compute Higgs branch Hasse diagrams compare with results obtained via other methods finding nearly perfect agreement.
