Defining polynomial

$f(x)$$=$$ x^{5} - x^{4} - 4 x^{3} + 3 x^{2} + 3 x - 1 $.

The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.

Roots:
$r_{ 1 }$ $=$ $ 9 + 20\cdot 23 + 11\cdot 23^{2} + 6\cdot 23^{3} + 11\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 12 + 11\cdot 23^{2} + 17\cdot 23^{3} + 20\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 13 + 4\cdot 23 + 7\cdot 23^{2} + 14\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 17 + 3\cdot 23 + 4\cdot 23^{2} + 4\cdot 23^{3} + 21\cdot 23^{4} +O\left(23^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 19 + 16\cdot 23 + 11\cdot 23^{2} + 17\cdot 23^{3} + 23^{4} +O\left(23^{ 5 }\right)$
