Description: Alternate proof of ruc 16183. This proof is a simple corollary of rpnnen 16167, which determines the exact cardinality of the reals. For an alternate proof discussed at mmcomplex.html#uncountable 16167, see ruc 16183. (Contributed by NM, 13-Oct-2004.) (Revised by Mario Carneiro, 13-May-2013.) (Proof modification is discouraged.)
