$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \frac{1}{2}(1 + \sqrt{-15})\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( 1 - \beta ) q^{2} + ( -3 - \beta ) q^{4} + ( -7 + 3 \beta ) q^{8} +O(q^{10})\) \( q + ( 1 - \beta ) q^{2} + ( -3 - \beta ) q^{4} + ( -7 + 3 \beta ) q^{8} + ( 5 + 7 \beta ) q^{16} + 14 q^{17} + ( -8 + 16 \beta ) q^{19} + ( -8 + 16 \beta ) q^{23} + ( 16 - 32 \beta ) q^{31} + ( 33 - 5 \beta ) q^{32} + ( 14 - 14 \beta ) q^{34} + ( 56 + 8 \beta ) q^{38} + ( 56 + 8 \beta ) q^{46} + ( -24 + 48 \beta ) q^{47} + 49 q^{49} + 86 q^{53} + 118 q^{61} + ( -112 - 16 \beta ) q^{62} + ( 13 - 33 \beta ) q^{64} + ( -42 - 14 \beta ) q^{68} + ( 88 - 56 \beta ) q^{76} + ( 32 - 64 \beta ) q^{79} + ( -16 + 32 \beta ) q^{83} + ( 88 - 56 \beta ) q^{92} + ( 168 + 24 \beta ) q^{94} + ( 49 - 49 \beta ) q^{98} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + q^{2} - 7q^{4} - 11q^{8} + O(q^{10}) \) \( 2q + q^{2} - 7q^{4} - 11q^{8} + 17q^{16} + 28q^{17} + 61q^{32} + 14q^{34} + 120q^{38} + 120q^{46} + 98q^{49} + 172q^{53} + 236q^{61} - 240q^{62} - 7q^{64} - 98q^{68} + 120q^{76} + 120q^{92} + 360q^{94} + 49q^{98} + O(q^{100}) \)
