Description: A version of en2lp 4525 for natural numbers, which does not require
ax-setind 4508.
Note: using this theorem and bj-nnelirr 13676, one can remove dependency on ax-setind 4508 from nntri2 6453 and nndcel 6459; one can actually remove more dependencies from these. (Contributed by BJ, 28-Nov-2019.) (Proof modification is discouraged.) |
