Description: Show that ax-c11 36183 can be derived from ax-c11n 36184 in the form of axc11n 2437. Normally, axc11 2441 should be used rather than ax-c11 36183, except by theorems specifically studying the latter's properties. Usage of this theorem is discouraged because it depends on ax-13 2379. Use the weaker axc11v 2262 when possible. (Contributed by NM, 16-May-2008.) (Proof shortened by Wolf Lammen, 21-Apr-2018.) (New usage is discouraged.) |
