Figure 3
Modification of the (3 + 1)-dimensional structure for the Ti2 atom according to the process of the shear operation for (a) step I (removal of some of the atoms), (b) step II (displacement of the rutile blocks by the vector [0 $[1\over2]$ 0]_r) and (c) step III (displacement of the blocks by the vector [ $[1\over2]$ 0 $[1\over4]$ ]_r). The description in (c) is equivalent to (d) in the standard embedding for the modulated structures.
