In the previous publications (E. Kogan and V. U. Nazarov, Phys. Rev. B {\bf85}, 115418 (2012) and E. Kogan, Graphene {\bf 2}, 74 (2013)) we presentedpoint group symmetry classification of energy bands in graphene. In the presentnote we generalize classification by considering the space group symmetry. Alsoin the framework of group theory we describe destruction of the Dirac points ingraphene by a supercell potential.
