Action on k-subsets

Further actions of which can be derived from are the actions of on the sets

of - subsets   of , , which are defined as follows:

 

The action is called - homogeneous if and only if the corresponding action of on is transitive. An obvious example is the natural action of on , it is -homogeneous for .
