We take the orbifold by a pair (g,δ), where g is a (possibly nongeometric) symmetry of C and δis a translation along Tn. We analyze the T-dualities of these models and show that in general they contain Atkin-Lehner type symmetries. This generalizes our previous work on N = 4 CHLmodels based on heterotic string theory on T 6 or type II on K3 × T 2 , as well.
