The Potts model is shown to exhibit a phase transition of continuous order on a Cayley tree. The leading nonanalytic part of the free energy midLmid Images involves a critical exponent Images going from one to infinity as the coupling goes f rom infinity to KBP, the Bethe-Peierls critical coupling.
