| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -108t^{24} + 216t^{20} - 1620t^{16} + 3024t^{12} - 1620t^{8} + 216t^{4}
- 108\]
\[B(t) = 432t^{36} - 1296t^{32} - 12960t^{28} + 42336t^{24} - 57024t^{20} +
57024t^{16} - 42336t^{12} + 12960t^{8} + 1296t^{4} - 432\]
