Abstract

FINDING: Chiral aperiodic monotile ("Spectre") discovered, with inflation rules linked to hexagonal lattice and √3 scaling factor. | MATH: The tile is a strictly chiral aperiodic monotile — no reflections allowed. Inflation rule involves scaling by √3 (≈1.732), which is the ratio of the long diagonal to side length in a regular hexagon. The tiling is based on a hexagonal lattice (6-fold rotational symmetry in the underlying lattice, but the tile itself breaks mirror symmetry). No explicit golden ratio or base-60 constants appear in the core discovery; the key geometric constant is √3. | CONNECTION: √3 is the scaling factor for hexagonal close packing and for the triangular lattice (dual to hexagonal).
