## $q$-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.

 $$f(q)$$ $$=$$ $$q + 2 \zeta_{6} q^{5} +O(q^{10})$$ $$q + 2 \zeta_{6} q^{5} + ( 2 - 2 \zeta_{6} ) q^{11} + 3 q^{13} + ( -8 + 8 \zeta_{6} ) q^{17} -\zeta_{6} q^{19} + 8 \zeta_{6} q^{23} + ( 1 - \zeta_{6} ) q^{25} -4 q^{29} + ( 3 - 3 \zeta_{6} ) q^{31} + \zeta_{6} q^{37} + 6 q^{41} + 11 q^{43} -6 \zeta_{6} q^{47} + ( -12 + 12 \zeta_{6} ) q^{53} + 4 q^{55} + ( -4 + 4 \zeta_{6} ) q^{59} -6 \zeta_{6} q^{61} + 6 \zeta_{6} q^{65} + ( -13 + 13 \zeta_{6} ) q^{67} + 10 q^{71} + ( -11 + 11 \zeta_{6} ) q^{73} + 3 \zeta_{6} q^{79} + 2 q^{83} -16 q^{85} + ( 2 - 2 \zeta_{6} ) q^{95} -10 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 2q^{5} + O(q^{10})$$ $$2q + 2q^{5} + 2q^{11} + 6q^{13} - 8q^{17} - q^{19} + 8q^{23} + q^{25} - 8q^{29} + 3q^{31} + q^{37} + 12q^{41} + 22q^{43} - 6q^{47} - 12q^{53} + 8q^{55} - 4q^{59} - 6q^{61} + 6q^{65} - 13q^{67} + 20q^{71} - 11q^{73} + 3q^{79} + 4q^{83} - 32q^{85} + 2q^{95} - 20q^{97} + O(q^{100})$$
