sigma Dk=   2n(n+1)/2       n^2+n+2      n^2+n


                            n(n+1)-1         n^2            n^2+n+2


 


                        n                      n                         n


sigma Dk=n^2+n             n^2+n+2              n^2+n


                         n^2+n-n            n^2                 n^2+n+2


 


                         n                 o                      0


sig Dk=            n^2+n               2              0


                           n^2                    0               n+2


 


                            n               0                  0


sig Dk=               n^2+n               2            0


                             n^2+n-n            0        n+2


dis gives
