## $q$-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.

Basis of coefficient ring

 $$\zeta_{12}$$ $$=$$ $$( \beta_{3} + 2\beta_1 ) / 8$$ (b3 + 2*b1) / 8 $$\zeta_{12}^{2}$$ $$=$$ $$( \beta_{2} + 2 ) / 4$$ (b2 + 2) / 4 $$\zeta_{12}^{3}$$ $$=$$ $$( \beta_{3} ) / 4$$ (b3) / 4

## Character values

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