Theorem cdlemg17b 30851
Description: Part of proof of Lemma G in [Crawley] p. 117, 4th line. Whenever (in their terminology) p  \/ q/0 (i.e. the sublattice from 0 to p  \/ q) contains precisely three atoms and g is not the identity, g(p) = q. See also comments under cdleme0nex 30479. (Contributed by NM, 8-May-2013.)
