Derivation of multidimensional superperiodic symmetry groups by using Mackay groups


Ljiljana Radović




The geometrical application of multiple antisymmmetry groups and Mackay groups for the derivation of multidimensional subperiodic groups is considered and illustrated by the direct derivation of 4-dimensional groups of the category $G_{4321}$ from the category $G_{21}$ by using Mackay 2-multiple antisymmetry groups. In general, symmetry groups of the category $G_{(r+2)(r+1)r\ldots}$ treated as a subcategory of the category $G_{(r+2)r\ldots}$ can be derived directly by using Mackay 2-multiple antisymmetry groups.
