> 2) 1-3-4 major differentials. With the 3-cycle ringing in every relative order *twice* in the course (once in each position with each parity), this gives a 8*7*6*2 = 672 change course, ie 224 change division. This could lend itself nicely to the 1-cycle (treble) just treble-bobbing, leading to a "lead" that appears to be a whole asymmetric surprise method (penultimate row can be 12436587, with a 1458 leadend change gives you 14236857, which is handy), but which when taken as a course could have double symmetry, etc. In other words, a sort of "fractal method".
I'm not sure this will work - the 1458 lead end changes the parity, and
in any case it would have to be rung variable hunt to get the treble in
each position relative to the 3-cycle.
