Description: Show that ax-10o 1679 can be derived from ax-10 1468. An open problem is
whether this theorem can be derived from ax-10 1468 and the others when
ax-11 1469 is replaced with ax-11o 1779. See theorem ax10 1680
for the
rederivation of ax-10 1468 from ax10o 1678.
Normally, ax10o 1678 should be used rather than ax-10o 1679, except by theorems specifically studying the latter's properties. (Contributed by NM, 16-May-2008.) |
