Theorem cdleme4gfv 36581
Description: Part of proof of Lemma D in [Crawley] p. 113. TODO: Can this replace uses of cdleme32a 36515? TODO: Can this be used to help prove the 𝑅 or 𝑆 case where 𝑋 is an atom? TODO: Would an antecedent transformer like cdleme46f2g2 36567 help? (Contributed by NM, 8-Apr-2013.)
