Commentary

From the K3 family: y^2 - (Lx+B)y = x(x+D)(x+E), where B = pq(L+p+q) - pE - qD, L = 446667T^2 + 471466T + 239031, p = 318552T^2 + 368554T - 72570, q = 733413T^2 - 45082T - 14960, D = 5(7174492962T^4 - 7114589515T^3 - 22069002960T^2 + 3909144679T - 205134150), E = 882769396002T^4 + 811447034567T^3 - 1174040743T^2 - 32493137198T - 2386325360; apply the two-neighbor construction with v=[−1,0,−1,−1,0,0,0,1,0,1,−1,1,−1,1,0,2,0] in the class-1 section basis; the new fiber class is (3,2,−v). Set u=(76792784t−99752376)/(−5945455t−7719380), then specialize at t=−37787/89181, equivalently u=11797785573064/463761119695.
