{title2=$\dim V=3$}

A three-dimensional representation. The isospin-one irreducible representation of SU(2) is a <triplet representation>[triplet] with third components $-1,0,+1$; the fundamental SU(3) <quark> representation is also a <triplet representation>[triplet] but belongs to a different group.
