Abstract：
A picture of the dibaryon system is proposed. If the fundamental particles of SU ₆group are three baryons p, n and Λwhich have spin 1/2, then the dibaryon system must be classified according to SU ₆group. SU ₆group connect the strange analogy state of spin 0 with strange analogy state of spin 1. The "original" mass difference between Λhyperon and nucleon leads to the SU ₆symmetry breaking. Then, SU ₃gives the mass relations between strange analogy states of same spin, and SU ₆gives mass relations between the different strange analogy states of spin 0 and 1.
