摘要

This paper completes a series of works in which the three-dimensional Euclidean realization of the system of constructions of algebraic geometry determines the three-level (cluster-helicoid-union of helicoids) scheme of the assembly of ordered tetravalent structures. The algebraic and topological properties of the second coordination sphere of the eight-dimensional lattice E (8) have been used to derive an ordered noncrystalline diamond-like structure. An a priori constructed model represents a helicoidal assembly of finite tubes (from allowably distorted aOE (c) 110 > diamond chains) with transverse pentacycles, hexacycles, and heptacycles and nonintegral screw axes. It has been assumed that similar structures can be formed in diamond-like thin films, gas hydrates, biological structures, nanostructures, and other ordered systems.
