Crystallography: An Introduction
If a pole is entered in the asymmetric face unit on the stereogram and operated
on by the symmetry 4/mmm, the result is a ditetragonal dipyramid, {hkl}, shown in
Fig. 9.7a. This form has two degrees of freedom. A ditetragonal dipyramid will be

Diplohedral ditetragonal class; {hkl). 20. If a centre of symmetry is added to the
elements of symmetry which distinguish the crystals of the last class, we obtain a
class which we shall denote as the diplohedral ditetragonal class of the
tetragonal ...
