$q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of a primitive root of unity $$\zeta_{6}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + ( 3 - 6 \zeta_{6} ) q^{7} +O(q^{10})$$ $$q + ( 3 - 6 \zeta_{6} ) q^{7} -5 q^{13} + ( 3 - 6 \zeta_{6} ) q^{19} + 5 q^{25} + ( 6 - 12 \zeta_{6} ) q^{31} + 11 q^{37} + ( -6 + 12 \zeta_{6} ) q^{43} -20 q^{49} - q^{61} + ( -9 + 18 \zeta_{6} ) q^{67} + 7 q^{73} + ( 3 - 6 \zeta_{6} ) q^{79} + ( -15 + 30 \zeta_{6} ) q^{91} + 19 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q - 10q^{13} + 10q^{25} + 22q^{37} - 40q^{49} - 2q^{61} + 14q^{73} + 38q^{97} + O(q^{100})$$
