Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 11 + 75\cdot 79 + 67\cdot 79^{2} + 47\cdot 79^{3} + 66\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 19 + 48\cdot 79 + 66\cdot 79^{2} + 63\cdot 79^{3} + 20\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 63 + 7\cdot 79 + 48\cdot 79^{2} + 29\cdot 79^{3} + 55\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 66 + 26\cdot 79 + 54\cdot 79^{2} + 16\cdot 79^{3} + 15\cdot 79^{4} +O\left(79^{ 5 }\right)$
