Description: Axiom ax-c11 34172 was the original version of ax-c11n 34173 ("n" for "new"),
before it was discovered (in May 2008) that the shorter ax-c11n 34173 could
replace it. It appears as Axiom scheme C11' in [Megill] p. 448 (p. 16 of
the preprint).
This axiom is obsolete and should no longer be used. It is proved above as theorem axc11 2314. (Contributed by NM, 10-May-1993.) (New usage is discouraged.) |
