The aim of this investigation is the computation, by implementation of algorithms of a third-order perturbation theory developed in an earlier paper, of numerical results that represent quantitatively the distortion of the structure of a polytropic star, distortion owing to either uniform or differential rapid rotation. The results presented are systematically compared with those of previous investigations. Reliability and accuracy of first- and second-order results are also discussed. The Fortran program implementing the codes of the theory is extensively described and specifically documented.
