Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{3}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\beta + 1) q^{3} + 5 q^{5} + ( - 9 \beta - 1) q^{7} + (2 \beta - 23) q^{9} + (13 \beta + 19) q^{11} + (28 \beta - 40) q^{13} + (5 \beta + 5) q^{15} - 17 q^{17} + (6 \beta + 90) q^{19} + ( - 10 \beta - 28) q^{21}+ \cdots + ( - 261 \beta - 359) q^{99}+O(q^{100}) \) Copy content Toggle raw display
