The 17 pages that link to Quasicrystal, each with the reason it gives.

• Crystal structureCompared with: It shows that ordered solids need not have a conventional repeating unit cell.

• Crystal latticeCompared with: Quasicrystals challenge the assumption that crystalline order requires a repeating lattice.

• Amorphous solidCompared with: It shows that nonperiodic structure can still possess long-range order unlike an amorphous solid.

• Bravais latticeCompared with: Its order can have rotational symmetries forbidden to periodic Bravais lattices.

• CrystallographyCompared with: It produces sharp diffraction despite lacking the periodic lattice assumed in conventional crystallography.

• Space groupCompared with: Quasicrystals are not classified by ordinary crystallographic space groups.

• CrystallinityCompared with: It challenges the assumption that ordered solids must repeat periodically.

• LatticeCompared with: Quasicrystals show that ordered atomic patterns need not arise from a periodic lattice.

• Crystallographic point groupCompared with: Quasicrystals can exhibit rotational symmetries forbidden to periodic lattices.

• Polycrystalline materialCompared with: Its order is neither a conventional crystal lattice nor a collection of ordinary grains.

• Crystallographic restriction theoremCompared with: Quasicrystals can have forbidden rotational symmetries because the theorem assumes periodicity.
