$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{8}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( \zeta_{8} - 2 \zeta_{8}^{3} ) q^{5} +O(q^{10})\) \( q + ( \zeta_{8} - 2 \zeta_{8}^{3} ) q^{5} + ( 5 + 5 \zeta_{8}^{2} ) q^{13} + 8 \zeta_{8} q^{17} + ( 4 - 3 \zeta_{8}^{2} ) q^{25} + ( -7 \zeta_{8} + 7 \zeta_{8}^{3} ) q^{29} + ( -7 + 7 \zeta_{8}^{2} ) q^{37} + ( -\zeta_{8} - \zeta_{8}^{3} ) q^{41} + 7 \zeta_{8}^{2} q^{49} -4 \zeta_{8}^{3} q^{53} -12 q^{61} + ( 15 \zeta_{8} - 5 \zeta_{8}^{3} ) q^{65} + ( 5 + 5 \zeta_{8}^{2} ) q^{73} + ( 16 + 8 \zeta_{8}^{2} ) q^{85} + ( 13 \zeta_{8} - 13 \zeta_{8}^{3} ) q^{89} + ( 5 - 5 \zeta_{8}^{2} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 4q + O(q^{10}) \) \( 4q + 20q^{13} + 16q^{25} - 28q^{37} - 48q^{61} + 20q^{73} + 64q^{85} + 20q^{97} + O(q^{100}) \)
