The sdg interacting-boson model is presented in the SU(3) tensor formalism. The interactions are decomposed according to their SU(3) tensor character. The existence of the SU(3)-seniority preserving operator is found to be important. The model is applied to /sup 168/Er. Energy levels and electromagnetic transitions are calculated. This model is shown to solve the problem of anharmonicity regarding the excitation energy of the first K/sup ..pi../ = 4/sup +/ band relative to that of the first K/sup ..pi../ = 2/sup +/ one. E4 transitions are calculated to give different predictions from those by the quasiparticle-phonon nuclear model.
