Valencies,y by comparison with Fig. 2-2, which represents the number 1. The appearance of a single unique point at once establishes a center of reference. The extension to Fig. 2-3, the number 2, is stupendous: instead of a single central point we have now . vertices, between which there can be a relation. Th

Statistical Symmetry,valencies of these elements toward each other. We have seen, furthermore, that the numbers of elements of different dimensionality are interrelated by the Euler-Schlaefli relation (equations 3-1 and 3-2), and that the valencies are restricted by two relations derived from the Euler-Schlaefli relatio

Degrees of Freedom,tex can move with . degrees of freedom, whereas on a curve (dimensionality .) it can move with only a single degree of freedom. In three-dimensional space a vertex has three degrees of freedom: three quantities are needed to specify its location.

Lattices and Lattice Complexes,by moving the entire lattice parallel to itself through an appropriate distance it can be brought into coincidence with itself (cf. Fig. 15-1). It follows that a lattice is infinite in extent. The points of any planar lattice may constitute the centers of hexagonal Dirichlet Domains; we saw in the p

Additional Space Fillers and their Lattice Complexes,be, truncated octahedron, and rhombohedral dodecahedron—fill space; all three have the maximum symmetry. There are, in addition, interesting lattice . whose Dirichlet Domains also, of course, fill space. Since the environments of lattice-complex points are identical, but not necessarily oriented par
