Abstract A missing piece is added to the Svetitsky-Yaffe conjecture. The spin model in the same universality class as the (2 + 1) d SU(4) theory, the 2 d Ashkin-Teller model, has a line of continuously varying critical exponents. The exponents measured in the gauge theory correspond best to the Potts point on the Ashkin-Teller line.
