Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 5 + 30\cdot 79 + 72\cdot 79^{2} + 33\cdot 79^{3} + 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 12 + 33\cdot 79 + 31\cdot 79^{2} + 8\cdot 79^{3} + 71\cdot 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 13 + 61\cdot 79 + 38\cdot 79^{2} + 10\cdot 79^{3} + 71\cdot 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 48 + 63\cdot 79 + 40\cdot 79^{2} + 69\cdot 79^{3} + 7\cdot 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
