In particular, structural realists have been correct to insist on the fundamental importance of symmetry groups in the foundations of quantum theory. Structural realist accounts of the metaphysics of theory change, such as Ladyman The existing entities described by quantum theory are organized into a hierarchy, in which a particular symmetry group occupies the top, most fundamental Similarly, Ladyman and Ross argue that, 'elementary particles are hypostatizations of sets of quantities that are invariant under the symmetry groups of particle physics' Unlike many more abstract accounts of structural realism, quantum theory provides GSR In particular, GSR places group structure at the top of the metaphysical hierarchy. example of angular momentum, the fundamental structure is the rotational symmetry group SO(3). approach to structural realism provided by Wigner's legacy, we elevated the rotation group SO(3)	./cache/work_x25adkztareqdmoj26gbfezc44.pdf	./txt/work_x25adkztareqdmoj26gbfezc44.txt
