Strangely enough I was aware of those examples, but I guess I asked for 
some such response. Seriously, I thought that Philip or some one else 
who understands these things might come up with something constructive 
about methods based upon a consistent rule which is applied without 
variation; e.g when treble leads make 2nds and 5ths and when 2nd leads 
make 4ths and 5ths gives 84 changes. Is there a similar rule of the kind 
"when this happens do this" that can produce the extent.
