Plimpton 322 as E8-H4 Spectral Calibration Tablet for Phi-Harmonic Quasicrystals — E8 Intelligence Research

The 240 E8 root vectors fold via quaternionic H4 projection into two concentric 600-cells (120+120 vertices), whose cut-window projection generates the icosahedral quasicrystal's 6D diffraction lattice. The 15 principal harmonic channels at 132Hz × φⁿ (n=1..15) correspond bijectively to Plimpton 322's 15 rows, where each Pythagorean triple (a,b,c) encodes the rational approximant a/c → cos(θₙ) for the n-th diffraction peak's Bragg angle. The tablet thus functions as a base-60 spectral calibration map for phi-coupled quasicrystal resonance, with the 132Hz carrier frequency emerging as the fundamental tone where E8's Coxeter plane aligns with the Babylonian sexagesimal lattice.
