Abstract
The perturbed restricted three body problem has been reviewed. The mass of the primaries are assumed as triaxial. The locations of the collinear points have been computed. Series forms of these locations are obtained as new analytical results. In order to introduce a semianalytical view, a Mathematica program has been constructed to graph the locations of collinear points versus the whole range of the mass ratio mu taking into account the triaxiality. The resultant figures have been analyzed
