"Here is a mathematics paper related to change ringing theory that people
might be amused to see. The main result can be interpreted as: any
permutation may be achieved by a link method with a bounded number of
changes of direction for each bell, regardless of the stage (specifically,
10 changes of direction per bell is enough)..."
Interesting. What is the maximum number of changes of direction a bell
needs at stages 8, 10, 12? What permutations at these stages require the
maximum changes of direction?
