In radial quantization, the ground states of a gauge theory on ADE singularities $R^4/\Gamma$ are characterized by flat connections that are maps from $\Gamma$ to the gauge group. We study Class S theory of type $A_1$ on a Riemann surface of genus $g>1$, without punctures. The fundamental building block of Class S theory is the trifundamental Trinion theory - a low energy limit of two M5 branes compactified on the three-punctured Riemann sphere. We show through the superconformal index, that the supersymmetric Casimir energy of the trifundamental theory imposes a constraint on the set of allowed flat connections, which agrees with the prediction of a duality relating the ground state Hilbert space of Class S on ADE singularities to the Hilbert space of a certain dual Chern-Simons theory whose gauge group is given by the McKay correspondence. The conjecture is shown to hold for $\Gamma=Z_k$, agreeing with the previous results of Benini et al. and Alday et al. Non-abelian generalizations of this duality are analyzed by considering the example of the dicyclic group Dic${}_2$, corresponding to gauge group SO$(8)$.
