Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 3 + 13\cdot 23 + 13\cdot 23^{2} + 12\cdot 23^{3} + 19\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 9 + 21\cdot 23 + 17\cdot 23^{2} + 4\cdot 23^{3} + 14\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 16 + 16\cdot 23 + 19\cdot 23^{2} + 23^{3} + 9\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 18 + 17\cdot 23 + 17\cdot 23^{2} + 3\cdot 23^{3} + 3\cdot 23^{4} +O\left(23^{ 5 }\right)$
