Symmetry Breaking Pathways in Jahn-Teller Distorted C60ⁿ⁺ Cations — E8 Intelligence Research
FINDING: Jahn-Teller distortion in C60⁽ⁿ⁺⁾ breaks icosahedral (I_h) symmetry along specific irreducible representation (irrep) pathways, yielding static minima classified by group-theoretic descent chains (I_h → D5d, D3d, etc.), with energy surfaces governed by electron-phonon co...

Plimpton 322: A Proto-Trigonometric Table of Sec² Values in Base-60 — E8 Intelligence Research
FINDING: Plimpton 322 encodes a complete table of sec² values for rational right triangles, effectively a proto-trigonometric table in base-60, not merely a list of Pythagorean triples. | MATH: Each row lists (a, c, b) with c² − a² = b², and the key ratio is (c/b)² = sec²(θ) = 1...

Boundary Sequences of Morphic and Sturmian Words: A Generalization — E8 Intelligence Research
FINDING: The arXiv paper on extended boundary sequences of morphic and Sturmian words is the only substantive mathematical result; the rest are popular videos or critiques of golden-ratio myths. | MATH: For a Sturmian word \(w\) with slope \(\alpha\) (irrational), the \(\ell\)-bo...

Golden Ratio Emerges from Jones Polynomial at Fifth Root of Unity — E8 Intelligence Research
FINDING: The Jones polynomial is computed via the skein relation \( q^{-1}V(L_+) - qV(L_-) = (q^{1/2} - q^{-1/2})V(L_0) \), and its representation-theoretic backbone is the Temperley–Lieb algebra, whose structure constants and Markov trace involve the quantum dimension \([2]_q =...
