Investigated symmetry properties and lattice projections relating to quasicrystals.
Identified that inflation factor φ scales tile types following Fibonacci rules.
Found ratios derived from φ govern essential properties like edge lengths in Penrose tiling.
Demonstrated 5-fold symmetry is achievable in aperiodic order, contrary to periodic crystals.

Abstract

FINDING: Penrose tiling uses golden ratio inflation-deflation to generate aperiodic order with 5-fold symmetry, linking Fibonacci numbers to quasicrystal lattice dynamics. MATH: - Golden ratio φ = (1+√5) /2 ≈ 1. 618, with reciprocal 1/φ = φ-1 ≈ 0. 618. - Inflation factor φ: each tile type (kite/dart or rhombus) scales by φ under substitution rules. - Fibonacci numbers Fₙ appear in tile counts: number of kites/darts after n inflations follows F₍+₁ and Fₙ. - Penrose tiling vertices correspond to 2D projection of 5D cubic lattice (root system A₄). CONNECTION: - Ratios 0. 618, 1. 618, 2. 618 (φ² = φ+1) govern tile edge lengths and area ratios. - 5-fold symmetry forbidden in periodic crystals; quasicrystals use φ-based irrational angles (72°, 36°). - Inflation-deflation mirrors self-similarity in icosahedral symmetry (3D quasicrystal).
