not that we went for huge complicated changes as I
recall. Only 6 bells.
I'd have thought the permutations and combinations of 6 bells could get
quite complicated - 720? Though you get into millions once you have 10 or
Did you get that from 6!, i. e. 6×5×4×3×2(×1)? But what makes
change-ringing so complicated is that you can't easily _get_ to all the
combinations: because of the inertia of the bells and their mechanism,
you can generally only change the period of any one bell .by a small
amount: you can go from 87654321 to 87654231, say. So I'm not sure if
all sequences are possible.
(Though thinking about it, they probably are - but you have to sequence
them in a complex order. The bell that rings fifth out of eight can only
move to fourth or sixth on the next peal, or something like that. Sort
of Gray code.)

that, you'd have to have a box for 'None of the above'."
