Abstract
We construct in an explict way the soliton equation corresponding to the affine Kac--Moody Lie algebra G2(1) together with their bihamiltonian structure. Moreover the Riccati equation satisfied by the generating function of the commuting Hamiltonians densities is also deduced. Finally we describe a way to deduce the bihamiltonian equations directly in terms of this latter functions
