Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 89 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 47 + 67\cdot 89 + 34\cdot 89^{2} + 6\cdot 89^{3} + 57\cdot 89^{4} +O\left(89^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 66 + 39\cdot 89 + 4\cdot 89^{2} + 86\cdot 89^{3} + 75\cdot 89^{4} +O\left(89^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 76 + 64\cdot 89 + 8\cdot 89^{2} + 54\cdot 89^{3} + 86\cdot 89^{4} +O\left(89^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 78 + 5\cdot 89 + 41\cdot 89^{2} + 31\cdot 89^{3} + 47\cdot 89^{4} +O\left(89^{ 5 }\right)$
