Theorem axc11n-16 2268
Description: This theorem shows that, given ax-c16 2223, we can derive a version of ax-c11n 2219. However, it is weaker than ax-c11n 2219 because it has a distinct variable requirement. (Contributed by Andrew Salmon, 27-Jul-2011.) (Proof modification is discouraged.) (New usage is discouraged.)
