Lyapunov timescale as a function of N for Goodman et al. (1993) (red bullets) compared to the various relativistic solutions. In blue we present the solutions using 1-PN pair-wise terms with a scaling to the speed of light of v/c = 0.010 and twice this value. For the EIH equations of motion we show the case for v/c = 0.010 in green, twice and four times this value. The top blue curve fits t_λ ≃ 0.255 + 13.43e^−0.371N for v/c = 0.005, and t_λ ≃ 0.051 + 5.50e^−0.115N for v/c = 0.010.
