Proportionality for Solid Coalitions
–PSC is defined like –PSC, but is based on the Hagenbach-Bischoff quota  instead of the Hare quota, and the number of voters in  must exceed  Hagenbach-Bischoff quotas. It is a more general form of the majority criterion because it allows for groups of supported candidates (solid coalitions) instead of just one candidate, and there may be more than one candidate that will be elected. Because some authors call the fraction  a Droop quota, –PSC is also known as the Droop proportionality criterion.
