Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{-3}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - \beta q^{3} - 4 \beta q^{7} - 3 q^{9} - 8 \beta q^{11} - 24 q^{13} + 24 q^{17} - 16 \beta q^{19} - 12 q^{21} + 20 \beta q^{23} + 3 \beta q^{27} - 10 q^{29} + 8 \beta q^{31} - 24 q^{33} - 24 q^{37} + \cdots + 24 \beta q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1200\mathbb{Z}\right)^\times\).

\(n\) \(401\) \(577\) \(751\) \(901\)
\(\chi(n)\) \(1\) \(1\) \(-1\) \(1\)

Embeddings

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