[r-t] Pitman's 13440 change compositions

[Robin Woolley]

f.w.i.w, I seem to recall from the time that the secret of the 
compositions was that, in a course, 7 and 8 are not in the same relative 
positions throughout.

I remember sitting on a bean bag listening to a test match (most like vs 
NZ) - and using pencil and paper to try to come up with something 
myself. I generated several true courses, one involving Lincolnshire, 
Yorkshire, Ospringe and one with the following pn: x5x6x5x36x4x23x234x7 
before I found something more interesting to do.

The advantage of this is, like the three-lead spliced peals, (obviously) 
that all you need to do is to put the courses together and the 
composition must be true. (True is the sense of no in-course falseness).

Best wishes
