 Ends in the same formation as the starting formation,

- 
 The Outside 6 Circulate within their distorted 6-dancer formation.  To Circulate,
    move forward to the next position within the Outside 6, turning if necessary  
    (not at all, 1/4, or 1/2) to take the original facing direction of the dancer that occupied
    the spot to which you are moving.  If you are facing a dancer on the Circulate path, 
    pass right shoulders and take that dancer's original opposite facing direction.
