A simple calculation for you I'm sure but one which I am too lazy to do!
How many leadheads are there on n bells which (keep the treble fixed)
and lead to courses of n-1 leads. (This is probably the number of
elements of a permutation group of order n-1 whose cycle is precisely
n-1 , although I have probably used the wrong terminology).  If a simple
formula isn't available then a table up to n="something sensible" would

Regular leadheads are labelled a, b, c etc., is there a similar
classification for irregular leadheads and if so what is it?
