$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -7077888t^{32} + 106168320t^{28} - 58392576t^{24} - 6635520t^{20} +
7354368t^{16} - 414720t^{12} - 228096t^{8} + 25920t^{4} - 108\]
\[B(t) = 7247757312t^{48} + 228304355328t^{44} - 472916164608t^{40} +
