Let p1,…, pk be k points (events) in (n+ 1)-dimensional Minkowski space R1, n. Using the
theory of hyperplane arrangements and chromatic polynomials, we obtain information on the
number of different orders in which the events can occur in different reference frames if the
events are sufficiently generic. We consider the question of what sets of orderings of the
points are possible and show a connection with sphere orders and the allowable sequences
of Goodman and Pollack.
