Spatial element, for games or construction or architecture and/or art, is composed of a parent tetrahedron together with other elements in pyramid and peak structures

摘要

The spatial element, for use in games or construction or architecture or technology and/or art, is an assembly of tetrahedrons as a polyhedron. The first element (S1) is a parent tetrahedron with four equilateral triangular surfaces (F1-F4) of the same dimensions, six equilateral edges and four corners where three triangular surfaces meet at each. At least one further element has seven surfaces, six peaks and eleven edges. Two parent tetrahedron surfaces have common edges and two peaks. At least one third element (S3), one-third of the parent tetrahedron, has a pyramid structure with four surfaces and three sides (S1'-S3').
