| Description: Derive the Axiom of Power Sets ax-pow 3481 from the Tarksi-Grothendieck axiom ax-groth 10131. That it follows is mentioned by Bob Solovay at http://www.cs.nyu.edu/pipermail/fom/2008-March/012783.html. Note that ax-pow 3481 is not used by the proof. (Contributed by Gérard Lang, 22-Jun-2009.) |
