| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -27t^{12} + 108t^{10} - 432t^{6} + 1728t^{2} - 1728\]
\[B(t) = 54t^{18} - 324t^{16} + 324t^{14} + 1512t^{12} - 5184t^{10} + 10368t^{8}
- 12096t^{6} - 10368t^{4} + 41472t^{2} - 27648\]
