摘要：
We study the q-state Potts antiferromagnet with q = 3 on the honeycomb lattice. Using an analytic argument together with a Monte Carlo simulation, we conclude that this model is disordered for all T greater than or equal to 0. We also calculate the ground state entropy to be S-0/k(B) = 0.507(10) and discuss this result.
