$q$-expansion
Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.
Basis of coefficient ring in terms of a root \(\nu\) of
\( x^{3} - x^{2} - 1351720x + 139588750 \)
:
| \(\beta_{1}\) | \(=\) |
\( 48\nu - 16 \)
|
| \(\beta_{2}\) | \(=\) |
\( 128\nu^{2} + 19680\nu - 115353376 \)
|
| \(\nu\) | \(=\) |
\( ( \beta _1 + 16 ) / 48 \)
|
