Symmetry adapted functions for double point groups II. Cubic point groups
Mathematical Proceedings of the Cambridge Philosophical Society, 1970AbstractA method of deriving the basis functions of the double-valued representations of a point group by the reduction of Kronecker products is described. The method has been used to derive expressions for these bases for cubic point groups for which the results are tabulated.

The three main kinds of point-group symbols in use today (Schoenflies symbols, Shubnikov symbols and Hermann–Mauguin symbols) are described and listed. International (Hermann–Mauguin) and Shubnikov symbols for symmetry elements and representatives for the lattice symmetry directions in the different crystal families are tabulated.

The 598 classes of nontrivial spin point groups are derived and tabulated. The relationship between classes of nontrivial spin point groups and the 32 classes of trivial magnetic point group and the 58 classes of nontrivial magnetic point groups is also given.

On infinite groups with points
Discrete Mathematics and Applications, 2002AbstractWe consider the notion of a point, give examples of groups with points and prove a theorem on the location of points in subgroups of infinite groups.

We now use the important concept of a mathematical group. The group elements are the symmetry operations. The group multiplication is the composition of symmetry operations as described in section 1.4.

Abstract The study of symmetry elements in two and three dimensions is followed by point groups, their derivation and recognition, including an interactive program for point group recognition. Euler’s theorem on the combination of rotations is discussed, and the physical properties of crystals and molecules in relation to their point ...
