Theorem bnj1018 32517

Description: Technical lemma for bnj69 32563. This lemma may no longer be used or have become an indirect lemma of the theorem in question (i.e. a lemma of a lemma... of the theorem). See bnj1018g 32516 for a less restrictive version requiring ax-13 2372. (Contributed by Jonathan Ben-Naim, 3-Jun-2011.) (New usage is discouraged.)
