Theorem cdleme42mgN 34577
Description: Part of proof of Lemma E in [Crawley] p. 113. TODO: FIX COMMENT . f preserves join: f(r s) = f(r) s, p. 115 10th line from bottom. TODO: Use instead of cdleme42mN 34576? Combine with cdleme42mN 34576? (Contributed by NM, 20-Mar-2013.) (New usage is discouraged.)
