Vacancy ordered phases (VOP) in the Al-Cu-Ni system have an arrangement of vacant and filled sites in the truncated Fibonacci sequence, along the  direction. In the absence of a geometrically enforced irrational lengthscale the limiting term in the sequence of VOP is not a quasicrystal. The implication of having commensurate lengthscales and quasiperiodicity (QP) in conjunction is studied using the concept of average lattices.
