A two-dimensional lattice-gas model with triangular symmetry is investigated by using the real-space renormalization group approach with blocks of different sizes and symmetries. We have calculated adsorption isotherms for different temperatures and coverage dependences for the thermodynamic factor and chemical diffusion coefficient.
