## $q$-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_{11} + \beta_{3}) q^{3} + ( - \beta_{7} + \beta_{6}) q^{4} + \beta_{2} q^{5} + (\beta_{10} + \beta_{8} + 2 \beta_{7} + \cdots -
