Hm... I get

               3    2          3    2          2    3          2    2
- 1/12 (3 I q10  q20  - 3 I q10  q21  - 3 I q10  q20  + 3 I q10  q21  q20

              4                2              4          5          2   3
 - 3 I q10 q20  + 2 q10 rho q21  + 3 I q10 q21  + 3 I q20  - 6 I q21 q20

                  2              4    2   /
   - 4 q20 rho q21  + 3 I q20 q21 ) Pi   /  (
                                        /

                     2      2      2       2      2
    (-2 q20 q10 - q21  + q10  + q20 ) (-q21  + q20 ))

!?
