Hi Victor,

I think the given formula is just an an example. It should somehow show, that only commutative operators ( *, + ) are used.

It could also be

     PI( A, B, C )
       = PI( A, C, B ) = PI( B, A, C ) = PI( C, A, B ) = PI( C, B, A)

With the formula:

     H(A)*H(B)+H(A)*H(C)+H(B)*H(C)+H(A)*H(B)*H(C)+H(A)+H(B)+H(C) =
     H(A)*H(C)+H(A)*H(B)+H(C)*H(B)+H(A)*H(C)*H(B)+H(A)+H(C)+H(B) =
     ........
