Theorem cdleme3 40224

Description: 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 40223 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 𝐹 ∈ 𝐴 ∧ ¬ 𝐹 ≤ 𝑊. Their proof provides no details of our lemmas cdleme3b 40216 through cdleme3 40224, so there may be a simpler proof that we have overlooked. (Contributed by NM, 7-Jun-2012.)
