Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 24 + 21\cdot 79 + 52\cdot 79^{2} + 40\cdot 79^{3} + 55\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 40 + 34\cdot 79 + 59\cdot 79^{2} + 9\cdot 79^{3} + 59\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 42 + 28\cdot 79 + 63\cdot 79^{2} + 71\cdot 79^{3} + 33\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 53 + 73\cdot 79 + 61\cdot 79^{2} + 35\cdot 79^{3} + 9\cdot 79^{4} +O\left(79^{ 5 }\right)$
