Say I have a chessboard (8x8=64 tiles, of course) and e.g. 22 pieces; tiles
are numbered 1 through 64); I want to deploy these 22 pieces throughout the
chessboard (black or white tiles don't matter); every time I do this I get a
set of 22 numbers (numbers of the tiles the pieces reside in); I am looking
for code that would generate for me all possible deployments of these 22
pieces (sets of 22 numbers); it should not be too complex but I cannot find a
clue to start off with... Please, please, give me a hint!:-)
