WebNov 7, 2024 · Crystallographic Axes. The symmetry of the Tetragonal System requires a set of 3 axes with two of the axes equal in length and the third axis either longer or shorter than the other two. The three axes are mutually perpendicular to each other. The two axes, equal in length are labelled a1 and a2. WebA slash ("/") character before the symbol m indicates a mirror plane perpendicular to the main axis of rotation. The crystallographic point groups may be classified according to the crystal system with which they are associated. Thus the point groups of the trigonal crystal system all possess a threefold axis, while those of the tetragonal and ...
