Zome green strut's √2:1). It is important to understand that, due to this length ratio, the blue-green struts having a rhombic cross section do not mathematically belong to the Zome system. Here is a mathematical definition of the Zome system, on which the physical Zometool construction set is based. It is defined in terms of the vector space formula_1, equipped with the standard inner product, also known as 3-dimensional Euclidean space. Let formula_2 denote the Golden ratio and let formula_3 denote the symmetry group of the configuration of vectors formula_4, formula_5, and formula_6. The group formula_3, an example of a Coxeter
