Theorem grothpw 9225
 Description: Derive the Axiom of Power Sets ax-pow 4630 from the Tarski-Grothendieck axiom ax-groth 9222. That it follows is mentioned by Bob Solovay at http://www.cs.nyu.edu/pipermail/fom/2008-March/012783.html. Note that ax-pow 4630 is not used by the proof. (Contributed by GĂ©rard Lang, 22-Jun-2009.) (New usage is discouraged.)
