The relations between Hall effect and symmetry are discussed for all 2| and 3|dimensional quasicrystals with crystallographically forbidden symmetries. The results show that the numbers of independent components of the Hall coefficient ( R H ) are one for 3|dimensional quasicrystals, two for those 2|dimensional quasicrystals whose symmetry group is non|Abelian, and three for those 2|dimensional quasicrystals whose symmetry group is Abelian, respectively. The quasicrystals with the same number of independent components have the same form of the components of R H .
