Symmetry-element diagrams of some point groups [adapted from Vainshtein (1994)[link]]. The point groups are specified by their Schoenflies and Hermann–Mauguin symbols. (a) C2 = 2, (b) [S_4 = \bar 4], (c) D3 = 32, (d) C4h = 4/m, (e) D6h = 6/m2/m2/m, (f) C3v = 3m, (g) [D_{3d} = \bar 3\, 2/m], (h) T = 23. [The cubic frame in part (h) has no crystallographic meaning: it has been included to aid visualization of the orientation of the symmetry elements.]
