    The section “Connected components” seems not quite right, or rather right only when d−1 is odd (as it is in classical relativity). When d−1 is even, point reflection in space P lies within SO+(d−1,1), so can’t lead to a different connected component.

    One fix would be to use reflection in a hyperplane. I’m not sure if there’s a cleaner / more symmetrical fix.

    Thanks for catching this. As a quick fix I have just edited to restrict d to 3 (here). Of course, better would be to type out the correct general discussion…

    Either way this section needs more discussion and/or more references. Please feel invited to edit, if you have the energy.
