I need this answer because it applies to a music theory question I have.
Lets say there are 12 on-off switches in a circle. How many unique possibilities are there when isometric or similar combinations are considered the same and say exactly 7 switches must be turned on? Such as:
on, on, on, off, off, off, off, off, on, on, on, on
is the same as
off, off, off, off, off, on, on, on, on, on, on, on
wow I would be very impressed and thankful if anyone has this solution and could explain it!
