$q$-expansion
comment: q-expansion
sage: f.q_expansion() # note that sage often uses an isomorphic number field
gp: mfcoefs(f, 20)
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
\( x^{3} - x^{2} - 52x - 38 \)
:
| \(\beta_{1}\) | \(=\) |
\( ( -\nu^{2} + 6\nu + 34 ) / 3 \)
|
| \(\beta_{2}\) | \(=\) |
\( \nu^{2} + 2\nu - 36 \)
|
| \(\nu\) | \(=\) |
\( ( \beta_{2} + 3\beta _1 + 2 ) / 8 \)
|
| \(\nu^{2}\) | \(=\) |
\( ( 3\beta_{2} - 3\beta _1 + 142 ) / 4 \)

Embeddings
For each embedding \(\iota_m\) of the coefficient field, the values \(\iota_m(a_n)\) are shown below.
