Theorem ax6o 1762
 Description: Show that the original axiom ax-6o 2187 can be derived from ax-6 1740 and others. See ax6 2197 for the rederivation of ax-6 1740 from ax-6o 2187. Normally, ax6o 1762 should be used rather than ax-6o 2187, except by theorems specifically studying the latter's properties. (Contributed by NM, 21-May-2008.)
