Theorem cdleme16b 36077
Description: Part of proof of Lemma E in [Crawley] p. 113, 3rd paragraph on p. 114, first part of 3rd sentence. 𝐹 and 𝐺 represent f(s) and f(t) respectively. It is unclear how this follows from s u t u, as the authors state, and we used a different proof. (Note: the antecedent ¬ 𝑇 (𝑃 𝑄) is not used.) (Contributed by NM, 11-Oct-2012.)
