Abstract
The 32-vertex model on a triangular lattice is solved exactly in two special cases. In one case the model is reducible to a three-spin Ising model and has the exponents alpha = alpha '=2/3. The other soluble case is the free-fermion model which exhibits the Ising behaviour but may possess multiple transitions.Keywords
