Abstract
In this short note, inspired by much recent activity centered around attempts to formulate various correspondences between the classification of affine SU(k) WZW modular-invariant partition functions and that of discrete finite subgroups of SU(k), we present a small and perhaps interesting observation in this light. In particular we show how the groups generated by the permutation of the terms in the exceptional Affine SU(2)-WZW invariants encode the corresponding exceptional SU(2) subgroups.
