Topology (contour line) and dynamical map (colour map) on the (e₁, e₂) plane for Case A, with constants L and G determined by the initial condition on the stable ACR solution (e₁, e₂, e₃, θ₁₂, Δϖ₁₂, θ₂₃, Δϖ₂₃) = (0.0124, 0.0237, 0.0128, 0, π, 0, π), which is indicated by a red dot on all maps. The eccentricity variations Δe_i are used as the stability indicator as labelled in each panel.
