This seven-dimensional grid, composed of 76800 deformations, was subject to the fivefold interpolation in all directions before it was used in the IWF procedure. This means that the IWF calculations have been performed on the grid containing 1 690 730 496(!) points. We have made such 7-dimensional analysis for more than 100 nuclei, for which the effect of minimization was greater than 300 keV. Results for these nuclei are shown in Table \[Octu\]. The rest of 127 cases shown in Table \[Octu\] are the test nuclei, in which the effect of the minimization was smaller than 0.3 MeV. The results for these additional nuclei allow to appreciate whether the (in principle exact) IWF method could produce a greater effect that the (inexact) minimization.

As one can see, the adopted procedure allowed to omit the problem of searching for a saddle by using the (inexact) minimization method which is not always reliable [@IIbarriers; @Moller2009]. For example, for Z=118 and N=165, the discussed effect
