No Rank-4 Icosahedral Fourier-Module Diffraction Data in Search Results — E8 Intelligence Research

FINDING: Search results are pedagogical XRD tutorials plus one Processing art demo; none contain rank-4 icosahedral Fourier-module diffraction data. | MATH: No equations, constants, or peak positions are present in the supplied material. | CONNECTION: None supported by evidence. | DEPTH: 1 Assessment of the supplied findings: 1. **Key mathematical insight**: None extractable. The five items are (a) crystallite-size broadening of XRD intensity, (b) peak-broadening factors, (c) phase identification via powder diffraction files, (d) a Processing-coded "looping quasicrystal" animation, (e) indexing cubic powder patterns. Only (e) carries real math, and it is cubic (integer hkl, 1/d² = (h²+k²+l²)/a²), the opposite of icosahedral. 2. **Equations/constants/ratios**: The only standard relations implied are Scherrer broadening (β = Kλ/(L cosθ)) and Bragg (λ = 2d sinθ). No golden-ratio constants appear. 3. **Geometric harmony**: Cubic indexing uses integer Miller indices — no 0.618, 1.618, 2 Author: Andrew Stewart Caldin, Independent Researcher, UK.
