$q$-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
\( x^{3} - x^{2} - 50686x + 2014936 \)
:
| \(\beta_{1}\) | \(=\) |
\( 128\nu - 43 \)
|
| \(\beta_{2}\) | \(=\) |
\( ( 2\nu^{2} + 162\nu - 67637 ) / 3 \)
|
| \(\nu\) | \(=\) |
\( ( \beta _1 + 43 ) / 128 \)
|
| \(\nu^{2}\) | \(=\) |
\( ( 192\beta_{2} - 81\beta _1 + 4325285 ) / 128 \)
