$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \frac{1}{2}(1 + \sqrt{57})\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( -4 - \beta ) q^{5} + ( 4 - 3 \beta ) q^{7} + 9 q^{9} +O(q^{10})\) \( q + ( -4 - \beta ) q^{5} + ( 4 - 3 \beta ) q^{7} + 9 q^{9} + ( 4 - 5 \beta ) q^{11} + ( -4 - 7 \beta ) q^{17} + 19 q^{19} -30 q^{23} + ( 5 + 9 \beta ) q^{25} + ( 26 + 11 \beta ) q^{35} + ( -44 + 3 \beta ) q^{43} + ( -36 - 9 \beta ) q^{45} + ( -44 + 13 \beta ) q^{47} + ( 93 - 15 \beta ) q^{49} + ( 54 + 21 \beta ) q^{55} + ( 44 + 15 \beta ) q^{61} + ( 36 - 27 \beta ) q^{63} + ( -4 + 33 \beta ) q^{73} + ( 226 - 17 \beta ) q^{77} + 81 q^{81} -90 q^{83} + ( 114 + 39 \beta ) q^{85} + ( -76 - 19 \beta ) q^{95} + ( 36 - 45 \beta ) q^{99} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 9q^{5} + 5q^{7} + 18q^{9} + O(q^{10}) \) \( 2q - 9q^{5} + 5q^{7} + 18q^{9} + 3q^{11} - 15q^{17} + 38q^{19} - 60q^{23} + 19q^{25} + 63q^{35} - 85q^{43} - 81q^{45} - 75q^{47} + 171q^{49} + 129q^{55} + 103q^{61} + 45q^{63} + 25q^{73} + 435q^{77} + 162q^{81} - 180q^{83} + 267q^{85} - 171q^{95} + 27q^{99} + O(q^{100}) \)
