The symmetric parameter that gives the relationship between the nodal point and the starting point of the Cartesian coordinations system, for which x = y = z = 0 holds true, is a centricity. The nodal point of a particular symmetry can be identical with this point. However, it can be placed at some specific positions or elsewhere. See the Table 2 for exact definitions.
Fig. 4 gives some further examples of orbital polyhedrons. The positions of x = y = z = 0 points are marked by the crossed circles in order to show the centricity of noncentric symmetries.
Table 3 lists all symmetries in accordance with the number of nonpolar or polar electrical axes comprising each particular orbital polyhedron. The lower is the number of electrical axes, the more polar is a particular symmetry, regardless of its nonpolar or polar character.
If we increase the number of electrical axes towards the infinity then three different situations evolve. In acentric symmetries belonging to H and T we obtain the orbital polyhedron consisting of an infinite number of electrical axes that are packed so closely that they melt into a single polar electrical axis of the highest symmetry Χ. See Figs. 3e and 3f.
In all centric symmetries except for ω ones the infinite number of electrical axes (nonpolar or polar) melt together and form a single nonpolar electrical axis of the highest symmetry Φ circumvented by an oppositely charged torus. Imagine the same situation as on the Fig. 3g but with the infinite n.
The infinite increase in the number of nonpolar or polar electrical axes in all ωtype symmetries ends in the highest symmetry Ω. The axes are so tightly packed that we cannot differentiate between their charges any more. An electroneutral sphere results.
If we consider the charges of the highest symmetries then we can conclude that the symmetry Χ is a polar one and the symmetry Ω an electroneutral one. The situation with the nonpolar Φ symmetry is different. Two configurations are possible. The first has a positive torus and negative lobes. The second is similar, yet the charges of its torus and lobes are reversed and consequently the configuration of the orbital polyhedron, too. The first has a leptoidal (spindleshaped), whereas the second a pithoidal (barrelshaped) morphology. Fig. 3g, shows the leptoidal situation. The spatial reversal of all electrical axes results in the pithoidal configuration.
