Description: A version of en2lp 4427 for natural numbers, which does not require
ax-setind 4410.
Note: using this theorem and bj-nnelirr 12834, one can remove dependency on ax-setind 4410 from nntri2 6342 and nndcel 6348; one can actually remove more dependencies from these. (Contributed by BJ, 28-Nov-2019.) (Proof modification is discouraged.) |
