| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -110592t^{24} + 1603584t^{20} - 103680t^{16} - 255744t^{12} - 6480t^{8}
+ 6264t^{4} - 27\]
\[B(t) = 14155776t^{36} + 456523776t^{32} - 583925760t^{28} - 216760320t^{24} +
