$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

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