Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 1 + 8\cdot 23^{2} + 16\cdot 23^{3} + 16\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 12 + 10\cdot 23 + 20\cdot 23^{2} + 6\cdot 23^{3} + 19\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 14 + 10\cdot 23 + 20\cdot 23^{3} + 17\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 20 + 23 + 17\cdot 23^{2} + 2\cdot 23^{3} + 15\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
Generators of the action on the roots
$r_1, \ldots, r_{ 4 }$
| Cycle notation |
| $(1,4,3,2)$ |
| $(1,3)(2,4)$ |
Character values on conjugacy classes
| Size | Order | Action on
$r_1, \ldots, r_{ 4 }$
| Character value |
| $1$ | $1$ | $()$ | $1$ |
| $1$ | $2$ | $(1,3)(2,4)$ | $-1$ |
| $1$ | $4$ | $(1,4,3,2)$ | $-\zeta_{4}$ |
| $1$ | $4$ | $(1,2,3,4)$ | $\zeta_{4}$ |
