$q$-expansion

comment: q-expansion

gp: mfcoefs(f, 20)

Coefficients of the $q$-expansion are expressed in terms of a primitive root of unity $\zeta_{15}$. We also show the integral $q$-expansion of the trace form.

$f(q)$	$=$	$ q + (\zeta_{15}^{7} + \cdots - \zeta_{15}^{3}) q^{2} + ( - \zeta_{15}^{7} + \zeta_{15}^{3} + 1) q^{3} + (2 \zeta_{15}^{7} + \zeta_{15}^{4} + \cdots - 1) q^{4} - \zeta_{15}^{6} q^{5} + ( -
