Theorem cdlemg17b 35950
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 35577. (Contributed by NM, 8-May-2013.)
