$q$-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.

\(f(q)\) \(=\) \( q + 2 q^{3} + ( -2 + 4 \zeta_{6} ) q^{5} + ( 3 - 2 \zeta_{6} ) q^{7} + q^{9} +O(q^{10})\) \( q + 2 q^{3} + ( -2 + 4 \zeta_{6} ) q^{5} + ( 3 - 2 \zeta_{6} ) q^{7} + q^{9} + ( -2 + 4 \zeta_{6} ) q^{11} + ( 2 - 4 \zeta_{6} ) q^{13} + ( -4 + 8 \zeta_{6} ) q^{15} + 2 q^{19} + ( 6 - 4 \zeta_{6} ) q^{21} + ( -2 + 4 \zeta_{6} ) q^{23} -7 q^{25} -4 q^{27} -6 q^{29} + 8 q^{31} + ( -4 + 8 \zeta_{6} ) q^{33} + ( 2 + 8 \zeta_{6} ) q^{35} + 2 q^{37} + ( 4 - 8 \zeta_{6} ) q^{39} + ( 4 - 8 \zeta_{6} ) q^{41} + ( 6 - 12 \zeta_{6} ) q^{43} + ( -2 + 4 \zeta_{6} ) q^{45} + ( 5 - 8 \zeta_{6} ) q^{49} -6 q^{53} -12 q^{55} + 4 q^{57} + 6 q^{59} + ( 2 - 4 \zeta_{6} ) q^{61} + ( 3 - 2 \zeta_{6} ) q^{63} + 12 q^{65} + ( -2 + 4 \zeta_{6} ) q^{67} + ( -4 + 8 \zeta_{6} ) q^{69} + ( 2 - 4 \zeta_{6} ) q^{71} + ( -4 + 8 \zeta_{6} ) q^{73} -14 q^{75} + ( 2 + 8 \zeta_{6} ) q^{77} + ( 2 - 4 \zeta_{6} ) q^{79} -11 q^{81} -6 q^{83} -12 q^{87} + ( 4 - 8 \zeta_{6} ) q^{89} + ( -2 - 8 \zeta_{6} ) q^{91} + 16 q^{93} + ( -4 + 8 \zeta_{6} ) q^{95} + ( -8 + 16 \zeta_{6} ) q^{97} + ( -2 + 4 \zeta_{6} ) q^{99} +O(q^{100})\)
