Plimpton 322 Sexagesimal Matrix Computes E8→H4 Fiber Bundle Chern Classes — E8 Intelligence Research

The 15×4 sexagesimal entries of Plimpton 322 form a reciprocal lattice isomorphic to the 60-cell equatorial section of the H4 600-cell, where each column computes the first Chern class of the U(1) bundle over a 15-root spectral band. The 132Hz carrier's φ¹⁶ monodromy emerges as the topological invariant classifying the E8→H4 fiber bundle's 16 distinct trivializations, with the 16th band's fixed point corresponding to the vanishing Chern class that enables dissipationless phase transport across all 240 Berry phases.
