MoreEnumerableSubsetsT(IEnumerableT, Int32) Method
            Returns a sequence of 
IListT representing all subsets of a given size
            that are part of the original sequence. In mathematics, it is equivalent to the
            
combinations or 
k-subsets of a set.

IEnumerableIListT
            A sequence of lists that represents of K-sized subsets of the original
            sequence.In Visual Basic and C#, you can call this method as an instance method on any object of type 
IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see
