not so easy a problem !
the 3 terms of each expression are:
(choose poles to use) *(distribute flags to chosen poles) *(pemute flags on each pole)
50000000: (8c1) (5c5) (5!)
41000000: (8c2) (5c4) (4!)
32000000: (8c2) (5c3) (3!2!)
31100000: (8c3) (5c3*2c1) (3!)
22100000: (8c3) (5c2*3c2) (2!2!)
21110000: (8c4) (5c2*3c1*2c1) (2!)
11111000: (8c5) (5c1*4c1*3c1*2c1)
compute and add up !
