# Laue class *T*_{h} – *m*-3

## Geometric class *T* – 23

Note: vectors along cubic diagonals [111], [1-1-1], [-11-1] and [-1-11] are abbreviated as **τ **=** a **+** b **+** c**, **τ**_{1} =** a **-** b **-** c**, **τ**_{2} =** **-**a **+** b **-** c** and **τ**_{3} =** **-**a **-** b **+** c**, respectively, for cubic groups.
