Ringing the changes, or 'change ringing' is where a set of bells is rung in every permutation.
So for (minimalist) example if you have three bells, A,B and C, they could be rung in the orders:
A,B,C
B,A,C
B,C,A
C,B,A
C,A,B
A,C,B

In each row, each bell is rung
once and only once; the only difference is their order.

Obviously, the number of permutations is n! (or n factorial), where n is the number of bells. This function grows quickly with increasing n.

I propose that convoys of people, on foot or in vehicles, could amuse themselves on long trips by reordering themselves in such a manner.
Where possible, horns should be sounded.

I'd like to see columns of soldiers walking down the road, reordering themselves from column to column,
Towers-of-Hanoi-style, ordered by height or weight.

Trying to control a 2 ton lump of bronze that you can't see, whirling at the end of a rather flimsy rope, with any 1/100 second misjudgement clearly audible to a few thousand bystanders, is not for wimps.

What makes you think we haven't ... ? Raising the bells, trying not to snap the backstay, getting a firm grip on ther sallie ... too much like hard work.
