Moddings by cyclic permutation symmetries are performed on four-dimensional strings, built from N=2 coset models of the type CPm=SU(m+1)/[SU(m)×U(1)]. For some illustrative cases, the massless chiral and antichiral states of E6 are computed. The extent of the equivalence between different conformal invariant theories which possess equal chiral rings is analyzed.
