Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} + 255x^{2} + 765 \)
|
The roots of $f$ are computed in $\Q_{ 59 }$ to precision 6.
Roots:
| $r_{ 1 }$ | $=$ |
\( 8 + 8\cdot 59 + 32\cdot 59^{2} + 46\cdot 59^{3} + 39\cdot 59^{4} + 8\cdot 59^{5} +O(59^{6})\)
|
| $r_{ 2 }$ | $=$ |
\( 25 + 16\cdot 59 + 9\cdot 59^{2} + 42\cdot 59^{3} + 4\cdot 59^{4} + 38\cdot 59^{5} +O(59^{6})\)
|
| $r_{ 3 }$ | $=$ |
\( 34 + 42\cdot 59 + 49\cdot 59^{2} + 16\cdot 59^{3} + 54\cdot 59^{4} + 20\cdot 59^{5} +O(59^{6})\)
|
| $r_{ 4 }$ | $=$ |
\( 51 + 50\cdot 59 + 26\cdot 59^{2} + 12\cdot 59^{3} + 19\cdot 59^{4} + 50\cdot 59^{5} +O(59^{6})\)

Character values on conjugacy classes
| Size | Order | Action on $r_1, \ldots, r_{ 4 }$ | Character value |

| $1$ | $2$ | $(1,4)(2,3)$ | $-1$ |
| $1$ | $4$ | $(1,3,4,2)$ | $-\zeta_{4}$ |
| $1$ | $4$ | $(1,2,4,3)$ | $\zeta_{4}$ |
