Theorem cardaleph 8251

Description: Given any transfinite cardinal number A, there is exactly one aleph that is equal to it. Here we compute that aleph explicitly. (Contributed by NM, 9-Nov-2003.) (Revised by Mario Carneiro, 2-Feb-2013.)

Assertion

Ref	Expression
cardaleph	|- ( ( om C_ A /\ ( card ` A ) = A ) -> A = ( aleph ` |^| { x e. On | A C_ ( aleph ` x ) } ) )

Distinct variable group:   x, A

Proof of Theorem cardaleph

Dummy variable y is distinct from all other variables.
