Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \frac{1}{2}(1 + \sqrt{-11})\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( - \beta + 3) q^{3} + ( - 2 \beta + 1) q^{5} + 2 q^{7} + ( - 5 \beta + 6) q^{9} + ( - 2 \beta + 1) q^{11} + ( - 5 \beta - 3) q^{15} + (4 \beta - 2) q^{17} + 4 q^{19} + ( - 2 \beta + 6) q^{21} + (2 \beta - 1) q^{23}+ \cdots + ( - 7 \beta - 24) q^{99}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 5 q^{3} + 4 q^{7} + 7 q^{9} - 11 q^{15} + 8 q^{19} + 10 q^{21} + 28 q^{25} - 10 q^{27} + 18 q^{31} - 11 q^{33} - 102 q^{37} + 44 q^{43} - 55 q^{45} - 90 q^{49} + 22 q^{51} - 22 q^{55} + 20 q^{57}+ \cdots - 55 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/132\mathbb{Z}\right)^\times\).

\(\chi(n)\) \(1\) \(1\) \(-1\)

Embeddings
