The authors describe the duality group Gamma =SU(3, 3, Z) for the Narain lattice of the T 6 /Z 3 orbifold and its action on the corresponding moduli space M 3.3 / Gamma , where M 3.3 =SU(3, 3)/(SU(3)(X)SU(3)(X)U(1)). A symplectic embedding of the momenta and winding numbers allows them to connect the orbifold lattice to the special geometry of M 3.3 . As an application, a formal expression for an automorphic function, which is a candidate for a non-perturbative superpotential, is given.
