One Integer, Three Generations

We present a rigid mathematical framework in which 27 independent Standard Model quantities—the gauge group, three coupling constants, three generations, eight fermion mass ratios, six mixing angles, two CP phases, the strong CP angle, the Higgs-to-\ (W\) mass ratio, the \ (Z\) -to-electron mass ratio, the electron-to-Planck mass ratio, one neutrino mass, and \ (₏₏₍\) —are determined by a single integer \ (a₁ = 5\), the unique solution of \ (a₁! = 4\, a₁ (a₁+1) \). The framework has no adjustable parameters beyond the electron mass \ (mₑ\) (a dimensional anchor): falsification of any single prediction invalidates the entire structure. From \ (a₁\) we derive \ (= (1+a₁) /2\) (golden ratio), the 600-cell (\ (a₁! = 120\) vertices), and \ (E₈\) (\ (h = a₁ (a₁+1) = 30\) ). We prove \ (N₆₄₍ = 3\) via Galois invariance and derive all nine fermion mass exponents through Galois conjugation and Casimir eigenvalues. The gauge group \ (SU (3) SU (2) U (1) \) is the unique compact Lie group whose adjoint restricts to \ (A₅\) with the icosahedral permutation decomposition (\ (11 = 3 + 8\) is the only valid partition). The CKM correction coefficients are ratios of \ (E₈\) Dynkin leg dimensions; the CP phase \ (₂₊₌ = (5) \) (0. 77%) is the Galois angle of \ (\) ; the strong CP problem is resolved by Galois invariance (\ (ₐ₂₃ = 0\) ). PMNS mixing angles follow from a Galois mixing matrix on \ (A₅\) irreps with eigenvalues \ (\0, N₆₄₍, a₁\\) and tribimaximal eigenvectors; \ (A₅\) Clebsch–Gordan corrections give all three angles within \ (0. 8\) of experiment.

Gravitational freeze-in is identified as the unique viable production mechanism. The cosmological constant matches \ (P = ^ (N - N₆₄₍) /2 - \) to 0. 13\ (\) (0. 33%).

Honest Limitations Electron mass \ (mₑ\) remains one free dimensional parameter (the only undetermined quantity is \ (f₂²\), the same ambiguity as in continuum NCG) Holonomy correction sector assignments are algebraically motivated, not derived from a single principle (Proposition 7: no-go for static geometry) Cosmological constant formula is a strong pattern without a spectral action mechanism Dark matter abundance ratio \ (₃₌/b = 7 - \) is speculative (reheating temperature not derived) Yukawa edge weights on the McKay graph: main chain forced, 3 branch weights remain open 4D nonlinear Regge completion and fermionic Lagrangian remain open Reproducible code: github. com/razvananghelina/One-Integer-Three-Generations — five self-contained Python scripts verifying coupling constants, 600-cell spectrum, fermion masses, Berry phase, and spectral action.
