Order
6
Conductor exponent
10
Values on generators of
\((\mathcal{O}_K/\mathfrak p^{ 10 })^\times/U_{\mathfrak{p}^{ 10 } }\)
, with \(\zeta=\frac{1+\sqrt{-3}}{2}\) a 6th root of unity
:
\(\begin{array}{l}
\chi^A\left(-b - 1 \right) &= \zeta^{ 5 }
\\
\chi^A\left(-3a\cdot b + 1 \right) &= \zeta^{ 2 }
\\
\chi^A\left(a^{2}b + 1 \right) &= \zeta^{ 4 }
\\
\chi^A\left(-3b + 1 \right) &= \zeta^{ 0 }
\end{array}
