Abstract
We construct a new grand unified theory based on the symmetry SU(6). In the model, the already-known particles in the standard model are assigned in two multiplets, [6] and [\overline{15}], by adding super-heavy neutrinos that should be interpreted as Majorana (sterile) neutrinos. The symmetry breaking is accomplished through Higgs mechanisms in two steps, that is it breaks first to SU(3)_C \otimes SU(3)_{DW} \otimes U(1)_B and subsequently to SU(2)_L \otimes U(1)_C \otimes U(1)_B that coincides to the standard model SU(2)_L \otimes U(1)_Y.
