$q$-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.

\(f(q)\) \(=\) \( q + q^{2} + q^{4} + \beta q^{5} + q^{8} +O(q^{10})\) \( q + q^{2} + q^{4} + \beta q^{5} + q^{8} + \beta q^{10} + q^{11} + \beta q^{13} + q^{16} -\beta q^{17} -2 \beta q^{19} + \beta q^{20} + q^{22} -4 q^{23} -3 q^{25} + \beta q^{26} -6 q^{29} -2 \beta q^{31} + q^{32} -\beta q^{34} -8 q^{37} -2 \beta q^{38} + \beta q^{40} -5 \beta q^{41} -8 q^{43} + q^{44} -4 q^{46} -6 \beta q^{47} -3 q^{50} + \beta q^{52} + \beta q^{55} -6 q^{58} -5 \beta q^{61} -2 \beta q^{62} + q^{64} + 2 q^{65} -8 q^{67} -\beta q^{68} -8 q^{71} + \beta q^{73} -8 q^{74} -2 \beta q^{76} + 4 q^{79} + \beta q^{80} -5 \beta q^{82} -2 \beta q^{83} -2 q^{85} -8 q^{86} + q^{88} + 7 \beta q^{89} -4 q^{92} -6 \beta q^{94} -4 q^{95} + 11 \beta q^{97} +O(q^{100})\)
