Thus, the orbitals do not associate with the 2b Wyckoff position of <em>p</em>6(mm), as is usually the case for graphene-like models, but with the two distinct Wyckoff positions that the <em>p</em>6(mm) 2b Wyckoff position subduces to when inversion symmetry is broken: this is precisely the 2b and 2c positions in <em>p</em>3.</li><li class="footnote" id="footnote-3"><a class="tag is-link" href="#citeref-3">3</a>Fukui, Hatsugai, & Suzuki, <em>Chern Numbers in Discretized Brillouin Zone: Efficient Method of Computing (Spin) Hall Conductances</em>, <a href="https://doi.org/10.1143/JPSJ.74.1674">J.
