Abstract
We show a close relationship between non-degenerate smooth commuting squares of II1-factors with horizontal inclusions of finite index and inclusions of subfactor planar algebras by showing that each leads to a construction of the other. One direction of this uses the Guionnet--Jones--Shlyakhtenko construction.
