Defining polynomial
$f(x)$ | $=$ | \( x^{5} - 2x^{3} - 4x^{2} - 6x - 4 \) . |
The roots of $f$ are computed in $\Q_{ 467 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ |
\( 49 + 50\cdot 467 + 28\cdot 467^{2} + 158\cdot 467^{3} + 139\cdot 467^{4} +O(467^{5})\)
$r_{ 2 }$ |
$=$ |
\( 59 + 367\cdot 467 + 148\cdot 467^{2} + 411\cdot 467^{3} + 177\cdot 467^{4} +O(467^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 102 + 228\cdot 467 + 80\cdot 467^{2} + 286\cdot 467^{3} + 364\cdot 467^{4} +O(467^{5})\)
| $r_{ 4 }$ |
$=$ |
\( 319 + 331\cdot 467 + 385\cdot 467^{2} + 388\cdot 467^{3} + 209\cdot 467^{4} +O(467^{5})\)
| $r_{ 5 }$ |
$=$ |
\( 405 + 423\cdot 467 + 290\cdot 467^{2} + 156\cdot 467^{3} + 42\cdot 467^{4} +O(467^{5})\)

Character values on conjugacy classes
Size | Order | Action on $r_1, \ldots, r_{ 5 }$ | Character value |
$1$ | $1$ | $()$ | $3$ |
$15$ | $2$ | $(1,2)(3,4)$ | $-1$ |
$20$ | $3$ | $(1,2,3)$ | $0$ |
$12$ | $5$ | $(1,2,3,4,5)$ | $-\zeta_{5}^{3} - \zeta_{5}^{2}$ |
$12$ | $5$ | $(1,3,4,5,2)$ | $\zeta_{5}^{3} + \zeta_{5}^{2} + 1$ |
