Line 11:
A larger subgroup is constructed [(4,4,4<sup>*</sup>)], index 8, as (2*2222) with gyration points removed, becomes (*22222222).
 
The symmetry can be doubled to [[842 symmetry]] by adding a bisecting mirror across the fundamental domains. The symmetry can be extended by 6, as [[832 symmetry]], by 3 bisecting mirrors per ___domain.
