And if you want to know what the 167,960 combinations are have a look in your
other thread and stick to a single thread.

Hi all,
instead of reenventing the wheel I turn to this group with my case:
assume a single column consisting of 20 cells; now, 11 cells contain the
number 1, others are empty. What I'm looking for is an elegant way of
elaborating all possible combinations of these 11 pieces as how they can be
scattered throughout 20 empty cells. Mind you, this could be done by hand
(ahhhhh), but a few combinations could be ommitted simply by mistake, and to
accomplish this would be a real drudgery; that's why I'm looking for an
algorithm to have this done for me. Any ideas?
