Quasiperiodicity in quasicrystals may exist in 1-, 2-, or 3-dimensions of physical spaces and is related to special irrational numbers such as the golden mean ≈ 1.6180339887 that is related to five-fold symmetry through the relation . Here, τ is the interesting irrational number that has the worst approximation by a truncated continued fraction, ------------------------------ [1445]
