This is the lowest symmetry class of the isometric system and contains only three fold and two fold axes. Most gersdorffite has an unordered arsenic-sulfur structure and therefore belongs to the higher Diploidal symmetry class. Gersdorffite is very similar to a nickel antimony sulfide called ullmannite.

Donald B Peck - Hermann-Mauguin Symmetry Symbols

The Isometric (Cubic) System The unique element of symmetry in the isometric system is the presence of 4 3-fold axes. The 4-fold axes are not present in all classes and as such are not the unique feature. Minerals in the isometric system comprise approximately 7% of all known minerals. About 2/3 of them are in the hexoctahedral class.
