t = 709/1079
Family y^2+(7t^2+309)xy-91(t^2-1)(t^2-25)(t^2-121)y=x^3 (Z/3Z K3 family, parameter t=709/1079). Family construction from the Layr Labs Elliptic Rank Challenge public repository, submission/board/3-r12-z3k3.ec (commit c8f82607a219df846ab80dd9e14ee09a2904d709, 2026-10-17). Not itself a repository curve: this t-value is not in that file.
