Theoremcdleme3 37492 Part of proof of Lemma E in [Crawley] p. 113. 𝐹 represents f(r). 𝑊 is the fiducial co-atom (hyperplane) w. Here and in cdleme3fa 37491 above, we show that f(r) W (4th line from bottom on p. 113), meaning it is an atom and not under w, which in our notation is expressed as 𝐹𝐴 ∧ ¬ 𝐹 𝑊. Their proof provides no details of our lemmas cdleme3b 37484 through cdleme3 37492, so there may be a simpler proof that we have overlooked. (Contributed by NM, 7-Jun-2012.)
