# Ringing the convoy

Ringing the changes for any form of convoy
 (+5) [vote for, against]

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.

 [8th] Don't knock it until you have tried it.

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.

P.S. you missed A,C,B

 // Don't knock it until you have tried it. //

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.

 Would this help people avoid accidents on long trips ?

 Or would it tend to cause them ?

 Just operating by instinct? Sort of the GW Bush "trust the gut" approach? It seems to be working out for you!

I used to trust my gut but then it turned on me. Turned huge.

Hah. Can't count to 3!. (Fixed)

Hardly surprising, since you oratorial talents seem more suited to your own Lower Rear Orofice ...
