Rhombic symmetry for defects in cubic crystals is often divided into two types:
Type I: C2 coincides with the [110] direction and C2’ and C2’’ with [001] and [1-10] directions respectively (or, σv and σv’ coincide with the planes (1-10) and (001)). Also belonging to type I are centres for which C2 coincides with [001] and σv and σv’ with (110) and (1-10).
Type II: C2 axis coincides with [001] and the axes C2’ and C2’’ with [100] and [010], (or, alternatively, σv and σv’ coincide with (010) and (100)).

Monoclinic symmetry for defects in cubic crystals is often divided into two types:
Type I: C2 coincides with <110> or σh with (110)
Type II: C2 coincides with <100> or σh with (100)

This table lists point group symmetries along with their symmetry operations, the order of the group (i.e. the number of symmetry operations) and common notations.maps to symbollinks to a correlation table, and ⊗ links to tables of products of irreducible representations. The group produced by combination with inversion is listed under "× i". This, in the case of crystolographic point groups, is the Laue class which corresponds to the symmetry of reciprocal space. Isomorphic groups are also listed where character tables are available.
