Infinite series of rhombic hexahedra : Ratio 1/ Ö3

The long diagonal of the smallest yellow rhombic hexahedron constitutes the short diagonal of the larger red rhombic hexahedron. The long and short diagonals coincide when the rhomic hexahedra are attached . Analogously the same relation holds for the larger green and blue rhombic hexahedra. Yhe rhombi consist of two equilateral triangles. The diagonals of the rhombi are in the ratio of 1 / Ö3 . The angels of the rhombi are 60^o and 120^o where three edges meet in vertices.When the rhombic hexahedra are attached , the two kinds of vertices coincide.
Such a series can continue in infinity.
