A layered 8-state Potts model with an aperiodic modulation of exchange couplings is studied. Depending on its geometric properties, the aperiodic sequence may induce a second order phase transition. Four sequences were considered: periodic, Thue-Morse (TM), Paper-Folding (PF) and Three Folding (TF).
