Theorem cdleme18d

Description: Part of proof of Lemma E in Crawley p. 114, 4th sentence of 4th paragraph. F , G , D , E represent f(s), f_s(r), f(t), f_t(r) respectively. We show f_s(r) = f_t(r) for all possible r (which must equal p or q in the case of exactly 3 atoms in p \/ q/0 , i.e., when -. E. r e. A ... ). (Contributed by NM, 12-Nov-2012)
