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

\(f(q)\) \(=\) \( q + 4 \beta q^{2} + (11 \beta - 1) q^{3} - 32 q^{4} + ( - 4 \beta - 88) q^{6} - 128 \beta q^{8} + ( - 22 \beta - 241) q^{9} + 458 \beta q^{11} + ( - 352 \beta + 32) q^{12} + 1024 q^{16} + 1004 \beta q^{17} + \cdots + ( - 110378 \beta + 20152) q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - 2 q^{3} - 64 q^{4} - 176 q^{6} - 482 q^{9} + 64 q^{12} + 2048 q^{16} + 352 q^{18} + 5764 q^{19} - 7328 q^{22} + 5632 q^{24} - 6250 q^{25} + 1450 q^{27} - 20152 q^{33} - 16064 q^{34} + 15424 q^{36}+ \cdots + 40304 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/24\mathbb{Z}\right)^\times\).
