Notation:
- / means "spinning" or touching from different shafts
- * means "on top of" or sharing the same shaft as the previous gear
- () means that it can be simplified down, for example (3/5*5/6) can be done 3/5/6
- [] is the minimum number of medium gears used like [3], [*] means it requires a large
