In the mood of recent posts,

a hunter sees a ducks flight of x rows
each row rank (n) has exactly (n) ducks

a shoot does not kill any duck, but the flight is split is 2 equal flights

( trivial 1+2+3 -> 2 x 1+2)

the flight had clearly something around 1000 to 10000 ducks

What is/are the possible solutions??

It happened that I found years ago a nice solution, but I am not 100% sure to get it back.
