If GG is a non-cyclic finite group, non-isomorphic GG-sets X,YX, Y may give rise to isomorphic permutation representations C[X]C[Y]\mathbb C[X ]\cong \mathbb C[Y]. Equivalently, the map from the Burnside ring to the rational representation ring of GG has a kernel. Its elements are called Brauer relations, and the purpose of this paper is to classify them in all finite groups, extending the Tornehave–Bouc classification in the case of pp-groups.
