$q$-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
\( x^{4} - 2x^{3} - 35x^{2} + 36x + 194 \)
:

\( ( -\nu^{3} + 11\nu^{2} + 12\nu - 182 ) / 19 \)
|
| \(\beta_{3}\) | \(=\) |
\( ( 11\nu^{3} + 12\nu^{2} - 265\nu - 392 ) / 57 \)
