Minimal super set of an charge spectrum relative to and
#minimalSuperSetGiven finite sets of possible charges and a charge spectrum , the **minimal super set** of is the collection of all charge spectra obtained by adding exactly one charge from the allowed sets to a component of that does not already contain it. Specifically, it is the union of the following sets, excluding itself: 1. If is empty, the set of spectra where is set to some and all other components remain as in . 2. If is empty, the set of spectra where is set to some and all other components remain as in . 3. The set of spectra where is replaced by for some . 4. The set of spectra where is replaced by for some .
