N2 - Some expected relations among modular invariants of N = 2 minimal models, namely (4)D ≈ (1) × (1), (10)E ≈ (1) × (2) and (28)E ≈ (1) × (3), are shown to hold exactly for the entire massless spectrum of string theories built out of these minimal models, not just for (2,2) but also (2,1) and (1,1) theories. Some new exceptional invariants of N = 2 tensor products are also discussed. Unlike (10)E and (28)E, these new invariants yield entirely new spectra.
