Abstract
We discuss the group theory relevant to the ground-state baryons in la rge N-c QCD. For very large representation, the group generators becom e classical variables. We find the form of the classical generators fo r the completely symmetric N index representation of SU(m) as N --> in finity and derive an integral formula for the matrix elements of an ar bitrary polynomial in the group generators between low-spin baryon sta tes in the large N limit.
