Figure 8
Left: any rectangular lattice Λ with a unit cell a × b has the obtuse superbase B with v1 = (a, 0), v2 = (0, b), v0 = (−a, −b), see Example 3.3 (op). Other lattices Λ have a rectangular cell 2a × 2b and an obtuse superbase B with v1 = (2a, 0), v2 = (−a, b), v0 = (−a, − b). Middle: RI(Λ) = [(\sqrt{b^2 - a^2}, a\sqrt{2}, a\sqrt{2})], a ≤ b ≤ [a\sqrt{3}]. Right: RI(Λ) = [(a\sqrt{2}, a\sqrt{2}, \sqrt{b^2 - a^2})], [a\sqrt{3}\leq b], see Example 3.3 (oc).
