   Where do you go after 8?  If you go to 1, the cylinders are right next   
   to each other.   
      
                                  1   
                               8     2   
                             7         3   
                               6     4   
                                  5   
      
   Using the odd number of cylinders it works out   
      
                                  1   
                                7   2   
                               6     3   
                                 5  4   
      
   Make sense?
