[r-t] Stedman Jump Triples

[Alexander Holroyd]

A few further remarks about this:

The 5040 is quite intriguing - it is a palindromic 21-part (with ss 
linkages), or, if we separate each part into its two mirrored halves , 
effectively a 42-part.  If I've got it right, that isn't possible in 
Stedman Triples!

The question of a bobs-only 5040 is open.  (I found some mutually true 
bobs-only blocks, but did not manage to joint them).

The method extends perfectly nicely to higher numbers, and retains the 
property or preserving the coursing order at the back (so the row 
213456789OE come up about half way through the plain course).

From a practical point of view it's actually moderately tricky to ring - 
the presence of jump changes at the front of the change all the time means 
that getting the leading right is a challenge in rhythm and bell-control.

Why not give it a try?!
