Higher Cardinals.

    Just an ideal question, possibly asked before, but is there an example of a Set which has cardinality of [tex]\aleph_{2}[/tex]?

    That's a tough one, since it depends on the assumptions you use. With the GCH, the set of all functions [itex]f:\mathbb{R}\rightarrow\mathbb{R}[/itex] has cardinality [itex]\aleph_2[/itex].
