Equation of state of the classical hard-disk fluid

We present data with an accuracy of 1 part in ${10}^4$ for the equation of state of the classical hard-disk fluid obtained by a Monte Carlo–molecular-dynamics method for a system of as many as 5822 particles when τ=${\rho }_0$/ρ ranges from τ=30 to 1.4, where ${\rho }_0$ is the value of the number density ρ for closest packing. The data are in excellent agreement with those obtained using a Levin approximant applied to the first six terms of the virial series.
