Explanation:

- Externality: Social facts are experienced externally to the individual. They exist outside the personal control and are part of broader societal forces.

- Freedom: Social facts are characterized by their coercive power, often limiting personal freedom. They shape behaviors and beliefs in a way that transcends individual choice.

- Constraint: This is a key feature. Social facts constrain individual actions through societal norms, laws, and shared beliefs.

- Generality: Social facts are general across a society, evident as collective patterns and not attributable to a single individual.

Given these explanations, Freedom is not a feature.
