When a M5 branes probes the singular locus of the D,E type ALE orbifold, the M5 brane exhibits fractionation, which corresponds to activating tensor branch moduli of the 6d N=(1,0) SCFT living on the M5. I explain how the fractionation patterns can be identified using the T^3 compactification, and propose some open problems related to M-theory and 6d SCFTs.
