Abstract
N M5-branes probing the intersection between the orbifold C^2/Zk and an E8 wall give rise to 6d (1,0) SCFTs known as A-type orbi-instantons. At fixed N and k, each element of Hom(Zk,E8) defines a different SCFT. The SCFTs are connected by Higgs branch RG flows. We determine the full hierarchy of these RG flows for any value of N and k. The hierarchy takes the form of an intricate Hasse diagram: each node represents an IR orbi-instanton (homomorphism), and each edge an allowed flow, compatibly with the 6d a-theorem. The partial order is defined via quiver subtraction of the 3d magnetic quivers associated with the 6d SCFTs.
