Let be a certain set of nonnegative symmetric matrices, such as the set of symmetric doubly stochastic matrices or the set, of symmetric permutation matrices. It is proven that a linear transformation mapping onto must be of the form X ↦ PtX P for some permutation matrix P except for several low dimensional cases.
