    • The results presented in this paper for the perfect triangular solid in the hard disk system were obtained by imposing a “single cell occupancy” constraint, rejecting all Monte Carlo moves that take a particle out of its (hexagonal) Wigner-Seitz cell. This ensures that no defects are produced during the Monte Carlo runs though the effect of the constraint on elastic moduli for the densities considered is negligible. Below a density of (Formula presented) this constraint becomes increasingly relevant

    • To eliminate the effects of finite size completely one has to use system sizes at least an order of magnitude larger than the correlation length. Our fits to Eq. (20) yield correlation lengths of about 2–3 lattice spacings, which implies that we would need a system of at least (Formula presented) particles taking care of periodic boundary conditions. This is much larger than the sizes used by Wojciechowski and Branka
