## $q$-expansion

gp: mfcoefs(f, 20)

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.

 $$\zeta_{12}$$ $$=$$ $$( \beta_{3} + 8\beta_1 ) / 32$$ (b3 + 8*b1) / 32 $$\zeta_{12}^{2}$$ $$=$$ $$( \beta_{2} + 8 ) / 16$$ (b2 + 8) / 16 $$\zeta_{12}^{3}$$ $$=$$ $$( \beta_1 ) / 2$$ (b1) / 2

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/576\mathbb{Z}\right)^\times$$.

## Embeddings

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