Abstract：
A picture of the dibaryon system is proposed. If the fundamental particles of SU₆ group are three baryons p, n and Λ which have spin 1/2, then the dibaryon system must be classified according to SU₆ group. SU₆ group connect the strange analogy state of spin 0 with strange analogy state of spin 1. The "original" mass difference between Λ hyperon and nucleon leads to the SU₆ symmetry breaking. Then, SU₃ gives the mass relations between strange analogy states of same spin, and SU₆ gives mass relations between the different strange analogy states of spin 0 and 1.
