| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -108t^{32} - 5184t^{24} - 110592t^{16} - 1327104t^{8} - 7077888\]
\[B(t) = 432t^{48} + 31104t^{40} + 663552t^{32} - 169869312t^{16} -
2038431744t^{8} - 7247757312\]
