 Baryon decuplet

The completely symmetric three-quark representation of flavour symmetry has dimension ten. Its weight diagram has rows $(Y,I)=(1,3/2),(0,1),(-1,1/2),(-2,0)$. It includes $uuu$ at the ${\Delta }^{++}$ weight and $sss$ at the ${\Omega }^{-}$ weight. A spatially symmetric three-quark colour singlet realizes this multiplet with spin $3/2$.
