Study discovers a chiral monotile, leading to significant advancements in tiling theory.
FINDING: Discovery of chiral aperiodic monotile ("Spectre") with inflation rules based on hexagonal lattice and √3 scaling factor. | MATH: The monotile's inflation rule scales the tiling by √3, consistent with the hexagonal lattice's fundamental ratio (√3 = 2 cos 30°). The chiral nature enforces a single handedness, eliminating reflections. Key constants: √3 ≈ 1.732, its reciprocal ≈ 0.577, and related ratios: 1/√3 ≈ 0.577, 2/√3 ≈ 1.155. The inflation matrix eigenvalues include √3 and 1/√3. | CONNECTION: √3 is the ratio of the height to side length in an equilateral triangle, central to hexagonal symmetry. The golden ratio φ (1.618) does not appear; instead, the tiling is rooted in the hexagonal lattice (crystallographic symmetry p6m). The inflation rule generates a self-similar structure with fractal dimension 2 (since area scales by 3 each inflation step). No base-60 or golden ratio connections. | DEPTH: 8 — Profound because it solves the long-standing aperiodic monotile problem with Author: Andrew Stewart Caldin, Independent Researcher, UK.
