Description: Show that ax-10o 1604 can be derived from ax-10 1396. An open problem is
whether this theorem can be derived from ax-10 1396 and the others when
ax-11 1397 is replaced with ax-11o 1704. See theorem ax10 1605
for the
rederivation of ax-10 1396 from ax10o 1603.
Normally, ax10o 1603 should be used rather than ax-10o 1604, except by theorems specifically studying the latter's properties. (Contributed by NM, 16-May-2008.) |
