We find the rules which count the energy levels of the three-state superintegrable chiral Potts model and demonstrate that these rules are complete. In the massive phase we show that the spectrum can be written in terms of two single-particle levels where one of the levels has the unusual property that it exists only for a limited range of momentum. We also discuss the relation of the counting rules to the S = 1 XXZ spin chain with anisotropy γ = 1 3π.
