SPT-sewing constructs all invertible domain walls in Abelian quantum doubles and new anchoring domain walls in 3D toric codes that interconvert point and loop excitations.
[72], with some adjustments, any action on the Pauli operators can given by the conjugation of the following canonical unitary operator U = ΩΠΩ′
