Donald B Peck - Determining Symmetry of Crystals: An Introduction

Galena has cubic symmetry. If we were to grasp the two ends of the axis through the centers of the top and bottom face of the galena cube Upper diagram, blue symbols , and turn the cube through 90 o, that cube would fill the same three dimensional space. Put another way, we would have the same view of the cube, even though from a different side.
