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

\(f(q)\) \(=\) \( q + \beta q^{2} + (\beta + 1) q^{3} + q^{4} + \beta q^{5} + (\beta + 3) q^{6} + q^{7} - \beta q^{8} + (2 \beta + 1) q^{9} + 3 q^{10} + ( - \beta + 3) q^{11} + (\beta + 1) q^{12} + \beta q^{14} + (\beta + 3) q^{15} + \cdots + (5 \beta - 3) q^{99} +O(q^{100}) \) Copy content Toggle raw display
