Definition

The point group of a crystal is called holohedral if it is identical to the point group of its lattice. The corresponding geometric crystal class is called a holohedry. In the three-dimensional space, there are seven holohedries: [math] {\bar 1}, 2/m, mmm, {\bar 3}m, 4/m mm, 6/m mm, m{\bar 3}m[/math].
