$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = 2\sqrt{3}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - q^{3} + q^{5} - q^{7} + q^{9} +O(q^{10})\) \( q - q^{3} + q^{5} - q^{7} + q^{9} + ( -2 + \beta ) q^{11} + \beta q^{13} - q^{15} + 2 q^{17} + ( -2 + \beta ) q^{19} + q^{21} + 2 \beta q^{23} + q^{25} - q^{27} + 2 q^{29} + ( -2 + \beta ) q^{31} + ( 2 - \beta ) q^{33} - q^{35} -2 q^{37} -\beta q^{39} + ( 2 + 2 \beta ) q^{41} -4 q^{43} + q^{45} + ( 4 - 2 \beta ) q^{47} + q^{49} -2 q^{51} + ( 4 + \beta ) q^{53} + ( -2 + \beta ) q^{55} + ( 2 - \beta ) q^{57} -4 \beta q^{59} + ( -2 - 2 \beta ) q^{61} - q^{63} + \beta q^{65} -2 \beta q^{67} -2 \beta q^{69} + ( 6 - 3 \beta ) q^{71} + ( 4 + \beta ) q^{73} - q^{75} + ( 2 - \beta ) q^{77} + 4 q^{79} + q^{81} + ( -8 + 2 \beta ) q^{83} + 2 q^{85} -2 q^{87} + ( -6 + 2 \beta ) q^{89} -\beta q^{91} + ( 2 - \beta ) q^{93} + ( -2 + \beta ) q^{95} + ( 16 - \beta ) q^{97} + ( -2 + \beta ) q^{99} +O(q^{100})\)
