Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 11 }$ to precision 9.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 4 + 4\cdot 11 + 9\cdot 11^{2} + 11^{3} + 6\cdot 11^{4} + 4\cdot 11^{5} + 9\cdot 11^{6} + 8\cdot 11^{7} + 6\cdot 11^{8} +O\left(11^{ 9 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 5 + 4\cdot 11 + 6\cdot 11^{2} + 10\cdot 11^{3} + 2\cdot 11^{4} + 7\cdot 11^{5} + 3\cdot 11^{6} + 2\cdot 11^{7} + 9\cdot 11^{8} +O\left(11^{ 9 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 7 + 6\cdot 11 + 4\cdot 11^{2} + 8\cdot 11^{4} + 3\cdot 11^{5} + 7\cdot 11^{6} + 8\cdot 11^{7} + 11^{8} +O\left(11^{ 9 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 8 + 6\cdot 11 + 11^{2} + 9\cdot 11^{3} + 4\cdot 11^{4} + 6\cdot 11^{5} + 11^{6} + 2\cdot 11^{7} + 4\cdot 11^{8} +O\left(11^{ 9 }\right)$ |
Generators of the action on the roots
$r_1, \ldots, r_{ 4 }$
| Cycle notation |
| $(1,4)$ |
