Theorem cdleme48fvg 36290
 Description: Remove 𝑃 ≠ 𝑄 condition in cdleme48fv 36289. TODO: Can this replace uses of cdleme32a 36231? TODO: Can this be used to help prove the 𝑅 or 𝑆 case where 𝑋 is an atom? TODO: Can this be proved more directly by eliminating 𝑃 ≠ 𝑄 in earlier theorems? Should this replace uses of cdleme48fv 36289? (Contributed by NM, 23-Apr-2013.)
