Possible Existence of a Boson Icosuplet

It is pointed out that the resonance ($B_1$) of the $\pi \omega$ system at 1220 MeV and the resonance ($B_2$) of the $\pi \rho$ system at 1200 MeV may form parts of an icosuplet consisting of a boson decuplet and its charge conjugate. Mixing of the two isotriplets in the decuplet and the conjugate decuplet is noted: $B_1$ and $B_2$ which are eigenstates of the operator $G$ are linear combinations of isotriplets in the {10} and {10}* representations. Consequences of this assumption are explored. The possibility that the $K\pi \pi$ resonance at 1175 MeV may belong to this icosuplet is also discussed.
