Yes, there are some (many maybe). Here's one.

There is a compliant extension of CS6 which goes at every fourth stage - 
10, 14, 18,... but the first of these stages (10) has a three-lead 
course (as does n=22). It consists of repeating the last section twice 
each time - x4x5x4x5, etc, with pivot bells increasing by four: 3, 7, 
11, 15,... although this may not be what Alan had in mind.

The Major is a 2-2-3 differential.

Best wishes
