This site is a table of crystallography groups. The table is composed of 32 classes of symmetry derived from observations of the external crystal form. From these 32 classes, 230 space groups are distinguishable using x-ray analysis. The site also features 3-D rotating examples of crystalline forms for each symmetry class. The illustrations are helpful for visualizing crystal forms.
