R4 point groups

Reports on Mathematical Physics, 1975
Abstract The first section of the paper contains a description of 118 isomorphism classes of R 4 point groups; the chosen presentations are related to certain structures of the groups such as direct sums and splitting extensions by cyclic groups. The second section gives a modification of the construction connecting 3- and 4-dimensional rotations

Point group symmetries

SPIE Proceedings, 2001
The form of macroscopic physical property tensors of a crystalline structure can be determined from its magnetic or non-magnetic point group symmetry. In a ferroic crystal containing two or more equally stable domains of the same structure but of different spatial orientation, macroscopic tensorial physical properties that are different in domains ...

Double groups of point groups

Molecular Physics, 1985
The representations of point groups appropriate to spin -1/2 particles are usually determined by considerations of a group of double the order of the point group under consideration, known as the double group. An alternative definition for double groups is given which makes use of the theory of central extensions and presentations of the point groups.
