[Samuel M. Austin]

What would be the formula to work out the following question and how would 
it apply to 12, 24 and 30 changes?

How many different methods could be rung using 3 bells, not having more than 
3 blows in one place and the method was to be say 18 changes long with no 
null changes?


Aye

PS

How many 48s of Minimus are there with not more than 6 blows in one place 
and no null changes?
