Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{15}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \beta_{2} q^{2} + ( - \beta_{14} - \beta_{13} - \beta_{2} + \cdots - 1) q^{3} + (\beta_{13} + \beta_{12} + \cdots - \beta_{2}) q^{4} + (\beta_{15} - \beta_{12} + \beta_{11} + \cdots - 1) q^{5} + ( - \beta_{15} + \beta_{14} + \cdots - \beta_1) q^{6}+ \cdots + (3 \beta_{15} + 8 \beta_{14} + \cdots + 4) q^{99}+O(q^{100}) \) Copy content Toggle raw display
