| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -27t^{10} - 1296t^{8} - 21168t^{6} - 124416t^{4} - 110592t^{2}\]
\[B(t) = 54t^{15} + 3888t^{13} + 110160t^{11} + 1524096t^{9} + 10119168t^{7} +
23887872t^{5} - 14155776t^{3}\]
