Coefficients of the \(q\)-expansion are expressed in terms of \(i = \sqrt{-1}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (i + 1) q^{2} + i q^{3} + 2 i q^{4} + 2 i q^{5} + (i - 1) q^{6} + 4 q^{7} + (2 i - 2) q^{8} - q^{9} + (2 i - 2) q^{10} + 2 i q^{11} - 2 q^{12} - 4 i q^{13} + (4 i + 4) q^{14} - 2 q^{15} - 4 q^{16} + \cdots - 2 i q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 2 q^{2} - 2 q^{6} + 8 q^{7} - 4 q^{8} - 2 q^{9} - 4 q^{10} - 4 q^{12} + 8 q^{14} - 4 q^{15} - 8 q^{16} - 2 q^{18} - 8 q^{20} - 4 q^{22} + 2 q^{23} - 4 q^{24} + 2 q^{25} + 8 q^{26} - 4 q^{30} - 12 q^{31}+ \cdots + 18 q^{98}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/552\mathbb{Z}\right)^\times\).
