A second method for determining an Exact Face begins by identifying the horizontal and vertical faces in relation to an Immediate face. The Immediate component is the face whose principal and sex is being considered as the origin. The vertical face is reached by a Minor Deosil turn from this Immediate face and is called the Mediate face. The Mediate component is represented by the vertical crystals of the Immediate face. In the example below these are 5&7 , 6&8 when read in the IMNR order of the face. The horizontal or Remote face, is reached by the same Minor Deosil from the Immediate plus a Major Deosil turn. The Remote component is established by the horizontal crystals of the Immediate face. In the example below these are 5&6 , 7&8. These three faces, when grouped together as Immediate, Mediate and Remote are called an astral toperm.
The above picture shows the astral toperm as EIY or 631. This demonstrates the anchoring of an Exact Face by giving the astral toperm using either the vowel or numeric form.
The numeric assignments for the vowels are shown in the chart below. E(x)=6 being the Immediate face, I(J)=3 being the Mediate face and Y(Q)=1 being the Remote face.
Another example: the astral toperm AUO=524.
