Abstract
FINDING: The Leech lattice (Λ₂₄) is the unique even unimodular lattice in 24 dimensions with no roots, constructed via orbifolding the E₈³ lattice or from Niemeier lattices through Lorentzian lattice methods; it underlies the Monster VOA at central charge 24. | MATH: Λ₂₄ has determinant 1, minimum norm 4, kissing number 196,560; theta series Θ_Λ₂₄(q) = 1 + 196,560q⁴ + 16,773,120q⁶ + ...; Golay code G₂₄ has parameters [24,12,8] with weight enumerator x²⁴ + 759x¹⁶y⁸ + 2576x¹²y¹² + 759x⁸y¹⁶ + y²⁴; Conway group Co₀ = Aut(Λ₂₄)/{±1} has order 8,315,553,613,086,720,000; Monster order |M| = 2⁴⁶·3²⁰·5⁹·7⁶·11²·13³·17·19·23·29·31·41·47·59·71 ≈ 8.08×10⁵³; VOA central charge c = 24; orbifold construction: Λ₂₄ ≅ (E₈³)/σ where σ is a triality automorphism, or via Lorentzian lattice II₂₅,₁ quotient by Weyl vector. | CONNECTION: The Leech lattice's 196,560 minimal vectors relate to the 0.618 ratio via the golden ratio φ appearing in the lattice's Gram matrix eigenvalues (the lattice is not φ-symmetric
