$q$-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.

\(f(q)\) \(=\) \( q - q^{2} + \beta q^{3} + q^{4} -\beta q^{6} - q^{8} + 5 q^{9} +O(q^{10})\) \( q - q^{2} + \beta q^{3} + q^{4} -\beta q^{6} - q^{8} + 5 q^{9} - q^{11} + \beta q^{12} -\beta q^{13} + q^{16} + \beta q^{17} -5 q^{18} + 2 \beta q^{19} + q^{22} + 8 q^{23} -\beta q^{24} -5 q^{25} + \beta q^{26} + 2 \beta q^{27} + 2 q^{29} + 3 \beta q^{31} - q^{32} -\beta q^{33} -\beta q^{34} + 5 q^{36} + 2 q^{37} -2 \beta q^{38} -8 q^{39} + \beta q^{41} -4 q^{43} - q^{44} -8 q^{46} + \beta q^{47} + \beta q^{48} + 5 q^{50} + 8 q^{51} -\beta q^{52} + 14 q^{53} -2 \beta q^{54} + 16 q^{57} -2 q^{58} -3 \beta q^{59} -3 \beta q^{61} -3 \beta q^{62} + q^{64} + \beta q^{66} + 4 q^{67} + \beta q^{68} + 8 \beta q^{69} -5 q^{72} -5 \beta q^{73} -2 q^{74} -5 \beta q^{75} + 2 \beta q^{76} + 8 q^{78} -16 q^{79} + q^{81} -\beta q^{82} -6 \beta q^{83} + 4 q^{86} + 2 \beta q^{87} + q^{88} -4 \beta q^{89} + 8 q^{92} + 24 q^{93} -\beta q^{94} -\beta q^{96} -6 \beta q^{97} -5 q^{99} +O(q^{100})\)
