Abstract: We discuss a grand unified theory (GUT) based on an GUT gauge group broken to its subgroups including a special subgroup. In the GUT on the six-dimensional (6D) orbifold space , one generation of the standard model fermions can be embedded into a 6D bulk Weyl fermion in the vector representation. We show that for a three-generation model, all the 6D and 4D gauge anomalies in the bulk and on the fixed points are canceled out without exotic chiral fermions at low energies.
