Theorem cdleme11 36079
Description: Part of proof of Lemma E in [Crawley] p. 113, 1st sentence of 3rd paragraph on p. 114. 𝐹 and 𝐺 represent f(s) and f(t) respectively. Their proof provides no details of our cdleme11a 36069 through cdleme11 36079, so there may be a simpler proof that we have overlooked. (Contributed by NM, 15-Jun-2012.)
