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.

 $$f(q)$$ $$=$$ $$q + ( -1 - \zeta_{6} ) q^{3} + ( 1 + 2 \zeta_{6} ) q^{7} + 3 \zeta_{6} q^{9} +O(q^{10})$$ $$q + ( -1 - \zeta_{6} ) q^{3} + ( 1 + 2 \zeta_{6} ) q^{7} + 3 \zeta_{6} q^{9} + ( 4 - 8 \zeta_{6} ) q^{13} + ( -4 + 2 \zeta_{6} ) q^{19} + ( 1 - 5 \zeta_{6} ) q^{21} + ( 3 - 6 \zeta_{6} ) q^{27} + ( 1 + \zeta_{6} ) q^{31} -\zeta_{6} q^{37} + ( -12 + 12 \zeta_{6} ) q^{39} + 13 q^{43} + ( -3 + 8 \zeta_{6} ) q^{49} + 6 q^{57} + ( 10 - 5 \zeta_{6} ) q^{61} + ( -6 + 9 \zeta_{6} ) q^{63} + ( 16 - 16 \zeta_{6} ) q^{67} + ( -9 - 9 \zeta_{6} ) q^{73} + 13 \zeta_{6} q^{79} + ( -9 + 9 \zeta_{6} ) q^{81} + ( 20 - 16 \zeta_{6} ) q^{91} -3 \zeta_{6} q^{93} + ( 11 - 22 \zeta_{6} ) q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 3q^{3} + 4q^{7} + 3q^{9} + O(q^{10})$$ $$2q - 3q^{3} + 4q^{7} + 3q^{9} - 6q^{19} - 3q^{21} + 3q^{31} - q^{37} - 12q^{39} + 26q^{43} + 2q^{49} + 12q^{57} + 15q^{61} - 3q^{63} + 16q^{67} - 27q^{73} + 13q^{79} - 9q^{81} + 24q^{91} - 3q^{93} + O(q^{100})$$
