Description: Derivation of set.mm's
original ax-11o 1803 from the shorter ax-11 1486 that
has replaced it.
An open problem is whether this theorem can be proved without relying on ax-16 1794 or ax-17 1506. Normally, ax11o 1802 should be used rather than ax-11o 1803, except by theorems specifically studying the latter's properties. (Contributed by NM, 3-Feb-2007.) |
