In this paper we illustrate the dynamics of the instanton representation inthe description of vacuum GR in minisuperspace for undensitized variables. Weuncover a new class of general solutions in both the degenerate and thenondegenerate sectors of the theory. Additionally, the individual sectors arepreserved under Hamiltonian evolution. Finally, we present an algorithm forconstructing general solutions by expansion about the isotropic sector.
