Figure 26
Schematic representation of the symmetry of the (a) MDO1 and (b) MDO2 polytypes of oxESEM (3b). Triangles are black on one and white on the other side. (Partial) symmetry operations of a layer and relating adjacent layers are indicated by the graphical symbols standardized in International Tables for Crystallography (Hahn, 2006aBB28). Additionally for operations with non-crystallographic intrinsic translations the printed symbol is given.
