These decimal numbers have equivalent values in trinary numbering. Three digit trinary expressions of these values can shed a bit more light in illustrating the way in which these six number values are fundamentally well chosen as the values for the edges, but showing the trinary digits and decimals together can be a bit confusing. The trinary representation will be omitted in order to remain clear about the simple arithmetic of this method. This is the only rule that guides the initial placement of numbering, and allows unambiguous number assignments to the 26 tetrahedron surface features. The number assigned to any one of the twelve Angles is found by adding the values of the two edges forming a given angle.
Faces is found by adding the values of the three edges forming a given face.
The number assigned to any one of the four Vertices is found by adding the values of the three edges that join at a given vertex. The method just described can also be applied to the numbering of the edges, vertices, and faces of the cube and the octahedron. The method undergoes a slight variation for each. The details of these applications of the method to the Cube and Octahedron I will leave to readers who like to solve puzzles. The point being made is that through this method of numbering 26 features, on each of the three forms, the count of 26 can be allocated as a significant memory place.
