How did the discovery of quasicrystals change the definition of crystals?

The discovery of solid structure changed the definition of crystal as follows:

The discovery of quasicrystals challenges the definition of crystal structure in traditional crystallography. Traditionally, crystals are considered to have three-dimensional periodic arrangement of atoms or molecules, which endows them with specific symmetry and macroscopic physical properties. However, quasicrystals show unique long-range order rather than periodic arrangement, which can not be described by the traditional periodic model of crystallography. The fifth and tenth symmetries of quasicrystals are completely different from the third and fourth symmetries that are common in nature, thus expanding people's understanding of crystal symmetry.
