NOTES
Making a selection of pieces is the same as assigning "yes" or "no" to each available piece.VARIATIONS
If you allow the selections to involve multiple copies of the same piece, it's a game of making multisets (or "bunches").
If you furthermore start caring about left-to-right placement of pieces, it's a game of making lists.

Many other games use the idea of selecting subsets.
In this game, certain selections are made "equal" -- they can be swapped out for one another.
