The abstract group concept. Material based on lectures by Peter Neumann.
http://www-history.mcs.st-andrews.ac.uk/history/HistTopics/Abstract_groups.html Binary Coordinate Systems -
Article by Steven H. Cullinane. Defines "Cartesian" coordinate systems for small finite geometries over the two-element field, and discusses geometrically simple generators for affine group actions.

The main point group symmetries of interest to defect physics by operation (reflection, rotations etc) and classification (trigonal, and cubic). Most point groups also have the associated character table on-line.
