Equation 677 Database

Size-77 twisted fiber-bundle magma satisfying Eq 677 (and Eq 255). Carrier Z/11 × F_7 with operation (x, s) ◇ (y, t) = ( x + 2·(y − x) mod 11 , α_d·s + β_d·t in F_7 ), where d = y − x mod 11. The base coefficient c = 2 is a primitive 10th root of unity mod 11 (Φ₁₀(2) = 2⁴ − 2³ + 2² − 2 + 1 ≡ 0 mod 11), which is exactly what Eq 677 forces on the base operation x + c·(y − x). The fiber field is F_7 = Z/7Z (prime field). The fiber coefficient pair (α_d, β_d) depends on the base difference d: d = 0: (α, β) = (4, 1) d = 1: (α, β) = (0, 1) d = 2: (α, β) = (6, 6) d = 3: (α, β) = (0, 1) d = 4: (α, β) = (0, 1) d = 5: (α, β) = (0, 1) d = 6: (α, β) = (6, 6) d = 7: (α, β) = (6, 6) d = 8: (α, β) = (6, 6) d = 9: (α, β) = (0, 1) d = 10: (α, β) = (6, 6) Eq 677 holds iff the pairs satisfy, for every d (writing e₁ = −d, e₂ = cd, e₃ = d(1 − c + c²), e₄ = −d/c, all mod 11): β_e₄·α_e₃ + β_e₄·β_e₃·α_e₂·β_e₁ = 1 and α_e₄ + β_e₄·β_e₃·(α_e₂·α_e₁ + β_e₂) = 0, with the d = 0 pair therefore satisfying the standard linear-677 conditions α₀β₀(1 + β₀²) = 1, α₀ + α₀²β₀² + β₀³ = 0. This family strictly generalizes the quadratic-residue-class bundles searched earlier (where (α_d, β_d) was constant on QR/non-QR classes): here the pair may vary with d arbitrarily. Found June 2026 by an exhaustive constraint solve over all per-d coefficient assignments; Eq 677 verified directly on the full Cayley table. The magma is NOT right-cancellative; not idempotent; it satisfies Eq 255 (consistent with the 677 ⇒ 255 finite conjecture). [text written by Claude]
