Okay, so I will use the {110} planes. Now I just have to locate the m3m symmetries, ie. two mirror planes and a threefold rotation around [111]. The rotation is easy and [111] is the same direction both in the crystal and the {110} coordinate system, but the two mirror planes either seem to be...

Thanks. The {110} normals work out fine, my only problem with these vectors is that they are not orthogonal. I'm not sure whether that is in fact a requirement for the coordinate system in this case, but I would have expected them to be orthogonal as we are considering a cubic crystal.

As I'm interested in the simplifications of property tensors due to crystal symmetry, I have been trying to find the symmetries of silicon (i.e. the diamond structure). As silicon belongs to the m3m point group I would e.g. expect to find a mirror plane perpendicular to the [100], [010] and...
