$q$-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.

\(f(q)\) \(=\) \( q - q^{3} + ( 2 + \beta ) q^{5} + q^{9} +O(q^{10})\) \( q - q^{3} + ( 2 + \beta ) q^{5} + q^{9} -2 q^{11} + ( 4 - \beta ) q^{13} + ( -2 - \beta ) q^{15} + ( -2 + 3 \beta ) q^{17} + 2 \beta q^{19} + ( 2 + 4 \beta ) q^{23} + ( 1 + 4 \beta ) q^{25} - q^{27} + ( 4 + 2 \beta ) q^{29} + ( -4 + 2 \beta ) q^{31} + 2 q^{33} + 4 q^{37} + ( -4 + \beta ) q^{39} + ( -2 - 3 \beta ) q^{41} + 4 \beta q^{43} + ( 2 + \beta ) q^{45} -2 \beta q^{47} + ( 2 - 3 \beta ) q^{51} + 2 q^{53} + ( -4 - 2 \beta ) q^{55} -2 \beta q^{57} + ( 4 - 2 \beta ) q^{59} + ( 8 + 3 \beta ) q^{61} + ( 6 + 2 \beta ) q^{65} -4 \beta q^{67} + ( -2 - 4 \beta ) q^{69} + ( 2 - 8 \beta ) q^{71} + ( -4 - 7 \beta ) q^{73} + ( -1 - 4 \beta ) q^{75} + ( -8 - 4 \beta ) q^{79} + q^{81} + ( 4 - 8 \beta ) q^{83} + ( 2 + 4 \beta ) q^{85} + ( -4 - 2 \beta ) q^{87} + ( 10 + 3 \beta ) q^{89} + ( 4 - 2 \beta ) q^{93} + ( 4 + 4 \beta ) q^{95} + ( -4 + \beta ) q^{97} -2 q^{99} +O(q^{100})\)
