constexpr TensorSymmetries sequant::density::rdm_symmetries  {.hermiticity = Hermiticity::Hermitian, .column = ColumnSymmetry::Symm}

densities and cumulants describe indistinguishable particles, hence are column symmetric, and are Hermitian by definition; both take part in the tensor hash, so every producer must spell them identically
