$q$-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.

\(f(q)\) \(=\) \( q + \beta q^{5} -2 q^{7} +O(q^{10})\) \( q + \beta q^{5} -2 q^{7} + 3 \beta q^{11} -2 \beta q^{13} -5 \beta q^{17} + ( 1 - 3 \beta ) q^{19} + \beta q^{23} + 3 q^{25} -10 q^{29} + 2 \beta q^{31} -2 \beta q^{35} -4 \beta q^{37} + 10 q^{41} -12 q^{43} -\beta q^{47} -3 q^{49} + 10 q^{53} -6 q^{55} + 12 q^{59} + 8 q^{61} + 4 q^{65} -10 \beta q^{67} + 8 q^{71} + 6 q^{73} -6 \beta q^{77} + 8 \beta q^{79} + 3 \beta q^{83} + 10 q^{85} + 6 q^{89} + 4 \beta q^{91} + ( 6 + \beta ) q^{95} -6 \beta q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 4q^{7} + O(q^{10}) \) \( 2q - 4q^{7} + 2q^{19} + 6q^{25} - 20q^{29} + 20q^{41} - 24q^{43} - 6q^{49} + 20q^{53} - 12q^{55} + 24q^{59} + 16q^{61} + 8q^{65} + 16q^{71} + 12q^{73} + 20q^{85} + 12q^{89} + 12q^{95} + O(q^{100}) \)
