Then WM's set of rationals must be a finite set, in contrast to everyone else's sets of rational, and FINITE ORDERED SETS ARE ALL WELL-ORDERED. So in WM's wild weird world of WMytheology, ALL ordered sets are well-ordered. And are reverse well-ordered as well (every non-empty such set has a smallest member as well as a largest member). That certainly must make WM's topology of the real number line a bit different, and removes any possibility of having infinite sequences or standard sort of continuity> In the finite domain, there is no difference.But in WM's finite domain there is a great deal of mathematics that simply does not take place.Brouwer could, with difficulty and with at last the theoretical existence of actual infiniteness, make it work.WM, with neither an actual infinity nor any such mathematical talent as Brouwer had, cannot come even close to making it work, so his WMytheology is a mathematical disaster area.--
