[r-t] Regular Minor Methods with a Plain Course Extent

[Mark Davies]

Interesting - probably not surprising there are a lot of them though, 
Graham! It's basically a large proportion (is it a twelfth?) of all the 
possible five-part compositions of Minor.

How about restricting the treble path to right-place, symmetrical lines? 
Still going to be a very big search space, but you'll get easier methods.
