AB - We offer further evidence that discreteness of the sort inherent in a causalset cannot, in and of itself, serve to break Poincar{\'e} invariance. Inparticular we prove that a Poisson sprinkling of Minkowski spacetime cannotendow spacetime with a distinguished spatial or temporal orientation, or with adistinguished lattice of spacetime points, or with a distinguished lattice oftimelike directions (corresponding respectively to breakings ofreflection-invariance, translation-invariance, and Lorentz invariance). Alongthe way we provide a proof from first principles of the zero-one law on whichour new arguments are based.
