$q$-expansion

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

\(f(q)\) \(=\) \( q - q^{2} + q^{4} + 2 \beta q^{5} - q^{8} +O(q^{10})\) \( q - q^{2} + q^{4} + 2 \beta q^{5} - q^{8} -2 \beta q^{10} + 2 q^{11} + q^{16} -\beta q^{17} + 5 \beta q^{19} + 2 \beta q^{20} -2 q^{22} + 4 q^{23} + 3 q^{25} -2 q^{29} -6 \beta q^{31} - q^{32} + \beta q^{34} + 10 q^{37} -5 \beta q^{38} -2 \beta q^{40} -7 \beta q^{41} + 2 q^{43} + 2 q^{44} -4 q^{46} + 2 \beta q^{47} -3 q^{50} + 2 q^{53} + 4 \beta q^{55} + 2 q^{58} -\beta q^{59} -2 \beta q^{61} + 6 \beta q^{62} + q^{64} + 12 q^{67} -\beta q^{68} + 12 q^{71} + \beta q^{73} -10 q^{74} + 5 \beta q^{76} -4 q^{79} + 2 \beta q^{80} + 7 \beta q^{82} + 7 \beta q^{83} -4 q^{85} -2 q^{86} -2 q^{88} -5 \beta q^{89} + 4 q^{92} -2 \beta q^{94} + 20 q^{95} -7 \beta q^{97} +O(q^{100})\)
