• a perhaps curious method: b is a reference set, perhaps all atoms in a certain molecule a is the working set, perhaps representing all displayed atoms For each set bit in b: a) if a is also set, then clear a's bit UNLESS b) if a is not set, then add to a all set bits of b Thus, if a equals b --> clear all if a is a subset of b, then --> b if b is a subset of a, then --> a not b if a only intersects with b, then --> a or b if a does not intersect with b, then a or b In "toggle" mode, when you click on any atom of the molecule, you want either: (a) all the atoms in the molecule to be displayed if not all are already displayed, or (b) the whole molecule to be hidden if all the atoms of the molecule are already displayed.
