Talk:Formal Logic/Preliminaries/Sets

I'm a little worried about defining omega as 'whole numbers' when different authors disagree on the definition of a whole number. How about 'non-negative integers'? Thickycat (discuss • contribs) 22:34, 27 September 2011 (UTC)

Incorrect notation "n ⟩ 2"?
In the section on ordered sets, I think the notation "n ⟩ 2" is incorrect in the sentence "These definitions are somewhat arbitrary, but it is nonetheless convenient for an n-tuple, n ⟩ 2, to be an n-1 tuple and indeed an ordered pair." Does this mean n is greater than two? If so, it should be written with a greater than sign "n > 2" instead of a left angle bracket. Otherwise, the meaning should be clarified.
