## Galois action

### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.
Roots:
 $r_{ 1 }$ $=$ $21 + 18\cdot 79 + 32\cdot 79^{2} + 60\cdot 79^{3} + 9\cdot 79^{4} +O\left(79^{ 5 }\right)$ $r_{ 2 }$ $=$ $33 + 22\cdot 79 + 13\cdot 79^{2} + 5\cdot 79^{3} + 59\cdot 79^{4} +O\left(79^{ 5 }\right)$ $r_{ 3 }$ $=$ $36 + 62\cdot 79 + 7\cdot 79^{2} + 14\cdot 79^{4} +O\left(79^{ 5 }\right)$ $r_{ 4 }$ $=$ $69 + 54\cdot 79 + 25\cdot 79^{2} + 13\cdot 79^{3} + 75\cdot 79^{4} +O\left(79^{ 5 }\right)$
