| Description: A version of en2lp 4696 for natural numbers, which does not require
ax-setind 4679.
Note: using this theorem and bj-nnelirr 16893, one can remove dependency on ax-setind 4679 from nntri2 6757 and nndcel 6763; one can actually remove more dependencies from these. (Contributed by BJ, 28-Nov-2019.) (Proof modification is discouraged.) |
