Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 22\cdot 23 + 18\cdot 23^{2} + 5\cdot 23^{3} + 19\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 5 + 2\cdot 23 + 4\cdot 23^{2} + 23^{3} + 2\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 19 + 21\cdot 23 + 22\cdot 23^{2} + 15\cdot 23^{3} + 23^{4} +O\left(23^{ 5 }\right)$
