Theorem cdlemg16 34270
Description: Part of proof of Lemma G of [Crawley] p. 116; 2nd line p. 117, which says that (our) cdlemg10 34254 "implies (2)" (of p. 116). No details are provided by the authors, so there may be a shorter proof; but ours requires the 14 lemmas, one using Desargues' law dalaw 33497, in order to make this inference. This final step eliminates the  ( R `  F )  =/=  ( R `  G ) condition from cdlemg12 34263. TODO: FIX COMMENT. TODO: should we also eliminate  P  =/=  Q here (or earlier)? Do it if we don't need to add it in for something else later. (Contributed by NM, 6-May-2013.)
