| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -27t^{12} - 864t^{10} - 10800t^{8} - 65664t^{6} - 193968t^{4} -
228096t^{2} - 27648\]
\[B(t) = 54t^{18} + 2592t^{16} + 53136t^{14} + 604800t^{12} + 4153680t^{10} +
