### Abstract

A relation is developed between point-group symmetries of light-scattering particles and symmetry relations for the electromagnetic scattering solution in the *T*-matrix formulation. A systematic derivation of a representation of symmetry operations is presented in the vector space on which the *T* matrix operates. From this the set of symmetry relations of the *T* matrix is obtained for various point groups. As examples several symmetry groups relevant to modeling atmospheric particles are treated, such as the *T* matrix can be verified, and new relations are found for *N*-fold axis of rotation.
