We give an explicit family of binomial generators for this lattice ideal, consisting of the generators of the ideal of the torus, (referred to as type I generators), a set of quadratic binomials corresponding to the cycles of length 4 in $\\G$ and which generate the \\emph{toric algebra of $\\G$} (type II generators) and a set of binomials of degree $q-1$ obtained combinatorially from $\\G$ (type III generators).
