Confusion also arises in the rhombohedral lattice which is alternatively described in a centred hexagonal (a=b, c, α=β=90º, γ=120º) or primitive rhombohedral (a=b=c, α=β=γ) setting.
Kebingungan juga muncul dalam kisi rombohedral yang secara alternatif digambarkan dalam heksagonal terpusat (a = b, c, α = β = 90º, γ = 120º) atau pengaturan rombohedral primitif. (a=b=c, α=β=γ) setting.
