> ordinal number[1] > 1: ie, a positive whole surreal number, rather than a positive whole real number Actually, ordinals have some additional contraints besides just "positive" and "whole" (eg ω−1 is not a ordinal), that just reduce to "positive whole" in the case of reals, although that doesn't change the actual point any.
