Rhombohedral structure

[unica]

Hello, everyone, can you give me the details of how to figure out the high-symmetry points of the first Brillouin zone of rhombohedral structure, such as bismuth? Thank you.

It seems that nobody fully understands your questions.
Do you master the geometrical properties of a reciprocal lattice, and it links with the direct lattice ? Do you master the metrics of crystalline lattices ?
