Combination of Linear and Icosahedral Structures

A module—call it a golden octet truss—is made from a tetrahedron and an octahedral part of a golden rhombohedron. It is used to combine linear and icosahedral structures by forming pairs of linear beams along the three main axes of space. Twenty such modules are assembled to form an icosahedral structure. The three pairs of beams can pass through each other without interference. At their intersection (node) four modules of each pair of beams coincide with the modules of the icosahedral structure.
