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

\(f(q)\) \(=\) \( q + 32 i q^{2} - 243 i q^{3} - 1024 q^{4} + 7776 q^{6} + 10556 i q^{7} - 32768 i q^{8} - 59049 q^{9} + 516912 q^{11} + 248832 i q^{12} - 1478402 i q^{13} - 337792 q^{14} + 1048576 q^{16} - 1265874 i q^{17} + \cdots - 30523136688 q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/150\mathbb{Z}\right)^\times\).

\(n\) \(101\) \(127\)
\(\chi(n)\) \(1\) \(-1\)

Embeddings

For each embedding \(\iota_m\) of the coefficient field, the values \(\iota_m(a_n)\) are shown below.
