## $q$-expansion

gp: mfcoefs(f, 20)

Coefficients of the $$q$$-expansion are expressed in terms of a basis $$1,\beta_1,\ldots,\beta_{11}$$ for the coefficient ring described below. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + ( - \beta_{11} + \beta_{5} + \beta_1) q^{2} + ( - \beta_{7} + \beta_{6}) q^{4} - \beta_{2} q^{5} + ( - \beta_{8} - \beta_{4} - \beta_{2} + \cdots + 1) q^{7}+ \cdots + ( - \beta_{10} -
