Four fold axis
WebA fourfold rotation about the c-axis, i.e. about the line 0,0,z, will have the corresponding symmetry operator -y,x,z. This axis has the written symbol "4". This axis has the written … WebFor example, there are two symmetric ways to arrange the subunits of a homotetramer. One is with a cyclic symmetry, in which the four subunits are related by a single 4-fold axis, called C4 symmetry, as shown in Figure 6. The other is a dihedral symmetry in which the four subunits are related by three 2-fold axes, called D2 symmetry (Figure 6).

WebTetragonal - The c axis is either the 4 fold rotation axis or the rotoinversion axis. Hexagonal - The c axis is the 6-fold, 3-fold, axis, or . Isometric - The equal length a axes are either the 3 4-fold rotation axes, rotoinversion axes, or, in cases where no 4 or axes are present, the 3 2-fold axes.
