Abstract: (Elsevier)
An invariant three-loop counterterm is exhibited for O(2) supergravity; its presence would imply nonrenormalizability. The analogous one-loop invariant due to O(2) supermatter coupling is also given. Involved are new conserved quantities due to the internal symmetry and to symmetry between fields separated by one spin unit.
