Figure 7 . Coupled 4d/2d/0d quiver gauge theory realizing intersecting M2-brane surface defects labeled by n R - and n L -fold symmetric representations in the four-dimensional theory of N 2 free hypermultiplets. Various superpotential couplings are turned on and are given in detail in [21]. The Higgsing prescription applied to SQCD precisely reproduces the partition function of this coupled
