The Relational Models Theory (RMT) of Alan Fiske is a framework for social relations that details four major types of interpersonal interactions: Communal Sharing (CS), Authority Ranking (AR), Equality Matching (EM), and Market Pricing (MP). These four types can also be combined and nested to form more complex social relations. Thus they are presented to be the elementary building blocks out of which all social relations are made.
John Bolender expounds on Fiske’s theory, by arguing that the four relationships are each described by the inherent mathematical symmetry of the social relation, and that all four can be ordered: in one way by inclusion (in the sense of mathematical group theory) and the opposite way by symmetry breaking (usually considered in physics). The symmetries are viewed as transformations which when applied, like a reorganization of the relationship, do not alter the substance or content of the relationship. CS is more symmetric than AR, which in turn is more symmetric than EM, which lastly is more symmetric than MP. For inclusion, the symmetries of MP are included in the symmetries of EM, those of EM in AR, and AR in CS. For symmetry breaking, a symmetry of CS can be broken to form AR, which in turn has a symmetry that can be broken to form EM, and so on to MP. Thus CS > AR > EM > MP in terms of transformations that preserve symmetry.
As we move from CS to MP, we add increasing structure to a social relation, a greater number of constraints. Additionally, consider symmetry operations in general in the context of equivalent exchange: symmetry by definition is an exchange of participants in a relation, a permutation such that the relation itself is unchanged, that is, equivalent.

Some changes: replacing the diagram and removing reference to J.-Y. Girard’s infernos of semantics. Also the very important insight from IEP: “The symmetries of solid matter form a subset of the symmetries of liquid matter which form a subset of the symmetries of gaseous matter which form a subset of the symmetries of plasma.”
