I think these plans might offer some quite interesting possibilities for
music. The group of order 21 that forms the part ends is a conjugate of
the one composed of rounds, queens, tittums and their cyclic rotations
(Price's [7:05]

)
The compositions given can't be transposed to have those part ends, but it
should be just as easy to get a composition starting from them. Then
there seems to be no reason why a large number of (or even all) 4-bell
runs could not be included...
