$q$-expansion

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

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