Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 6 + 39\cdot 79 + 47\cdot 79^{2} + 14\cdot 79^{3} + 57\cdot 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 13 + 47\cdot 79 + 65\cdot 79^{2} + 42\cdot 79^{3} + 27\cdot 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 29 + 47\cdot 79 + 75\cdot 79^{2} + 58\cdot 79^{3} + 64\cdot 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 30 + 30\cdot 79 + 9\cdot 79^{2} + 15\cdot 79^{3} + 42\cdot 79^{4} +O\left(79^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
