Although it is seldom recognized, a similar form of self-reference appears in the study of "group representations", and more generally, in the study of homomorphic representations of any mathematical structure. In particular, this type of ESR arises from the "regular representation" of a group in terms of its action on itself, that is, in the collection of effects that each element has on the all the individual elements of the group. | Although it is seldom recognized, a similar form of self-reference appears in the study of "group representations", and more generally, in the study of homomorphic representations of any mathematical structure.
