$q$-expansion
Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3\) 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

:

\( ( \nu^{3} + 88\nu^{2} - 88\nu - 7921 ) / 7832 \)
|
| \(\beta_{2}\) | \(=\) |
\( ( -\nu^{3} + \nu^{2} + 177\nu ) / 89 \)
|
| \(\beta_{3}\) | \(=\) |
\( ( \nu^{3} + 88\nu - 177 ) / 88 \)
|
| \(\nu\) | \(=\) |
\( ( \beta_{3} + \beta_{2} - \beta _1 + 1 ) / 3 \)

\( ( -\beta_{3} + 2\beta_{2} + 265\beta _1 + 266 ) / 3 \)
