Theorem cdleme7 30983
Description: Part of proof of Lemma E in [Crawley] p. 113.  G and  F represent fs(r) and f(s) respectively.  W is the fiducial co-atom (hyperplane) that they call w. Here and in cdleme7ga 30982 above, we show that fs(r)  e. W (top of p. 114), meaning it is an atom and not under w, which in our notation is expressed as  G  e.  A  /\  -.  G  .<_  W. (Note that we do not have a symbol for their W.) Their proof provides no details of our cdleme7aa 30976 through cdleme7 30983, so there may be a simpler proof that we have overlooked.
