The well known hydrostatic equilibrium equations of a gravitating rapidly rotating superdense configuration in post-Newtonian approximation have a bifurcation point in their solutions. Here, it is shown that the bifurcation point problem can be reduced to a real solution of a cubic algebraic equation in a domain of physical values of some parameters.
