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.

\(f(q)\) \(=\) \( q - \beta_{3} q^{2} + \beta_{5} q^{3} + ( - \beta_{8} + 2) q^{4} + \beta_{11} q^{5} + \beta_1 q^{6} + (\beta_{9} - 2 \beta_{3}) q^{8} - 3 q^{9} + \beta_{6} q^{10} + (\beta_{14} + 2 \beta_{5}) q^{12} + \beta_{10} q^{15}+ \cdots + ( - 3 \beta_{6} + 4 \beta_1) q^{96}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 16 q + 32 q^{4} - 48 q^{9} + 64 q^{16} - 80 q^{25} - 96 q^{36} + 128 q^{64} + 144 q^{81}+O(q^{100}) \) Copy content Toggle raw display
