Its band structure exhibits two Dirac points (DPs) that are separated by a nearly flat band. We present a procedure which we employed to identify eigenfrequencies and to separate the eigenstates according to their transformation properties under rotation by 60 degree into the three C3 subspaces. This allows us to verify previous numerical results of Ref.
