$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{13}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - q^{5} + ( 1 + \beta ) q^{7} +O(q^{10})\) \( q - q^{5} + ( 1 + \beta ) q^{7} - q^{11} + ( -1 - \beta ) q^{13} + ( -3 - \beta ) q^{17} -2 \beta q^{19} + q^{25} -8 q^{29} + ( 2 + 2 \beta ) q^{31} + ( -1 - \beta ) q^{35} + ( 4 - 2 \beta ) q^{37} -8 q^{41} + ( -7 + \beta ) q^{43} + ( -2 + 2 \beta ) q^{47} + ( 7 + 2 \beta ) q^{49} -2 q^{53} + q^{55} -8 q^{59} + 2 \beta q^{61} + ( 1 + \beta ) q^{65} -4 q^{67} + 4 \beta q^{71} + ( -3 + \beta ) q^{73} + ( -1 - \beta ) q^{77} + ( -4 - 2 \beta ) q^{79} + ( 7 + \beta ) q^{83} + ( 3 + \beta ) q^{85} -6 q^{89} + ( -14 - 2 \beta ) q^{91} + 2 \beta q^{95} + ( 2 - 4 \beta ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - 2 q^{5} + 2 q^{7} + O(q^{10}) \) \( 2 q - 2 q^{5} + 2 q^{7} - 2 q^{11} - 2 q^{13} - 6 q^{17} + 2 q^{25} - 16 q^{29} + 4 q^{31} - 2 q^{35} + 8 q^{37} - 16 q^{41} - 14 q^{43} - 4 q^{47} + 14 q^{49} - 4 q^{53} + 2 q^{55} - 16 q^{59} + 2 q^{65} - 8 q^{67} - 6 q^{73} - 2 q^{77} - 8 q^{79} + 14 q^{83} + 6 q^{85} - 12 q^{89} - 28 q^{91} + 4 q^{97} + O(q^{100}) \)
