Theorem cdleme4gfv 31318
Description: Part of proof of Lemma D in [Crawley] p. 113. TODO: Can this replace uses of cdleme32a 31252? 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 31304 help? (Contributed by NM, 8-Apr-2013.)
