Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = 2\sqrt{31}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\beta - 6) q^{5} + ( - \beta + 12) q^{7} - 11 q^{11} + (5 \beta - 4) q^{13} + ( - 6 \beta + 14) q^{17} + (2 \beta + 34) q^{19} + ( - 7 \beta - 134) q^{23} + ( - 12 \beta + 35) q^{25} + (4 \beta + 130) q^{29}+ \cdots + ( - 72 \beta + 250) q^{97}+O(q^{100}) \) Copy content Toggle raw display
