Basic invariants
Defining polynomial
$f(x)$ | $=$ | \(x^{2} - x + 896\) . |
The roots of $f$ are computed in $\Q_{ 7 }$ to precision 5.
Roots:
$r_{ 1 }$ |
$=$ |
\( 2\cdot 7 + 7^{2} + 2\cdot 7^{4} +O(7^{5})\)
|
$r_{ 2 }$ |
$=$ |
\( 1 + 5\cdot 7 + 5\cdot 7^{2} + 6\cdot 7^{3} + 4\cdot 7^{4} +O(7^{5})\)
|
Generators of the action on the roots
$ r_{ 1 }, r_{ 2 } $
Character values on conjugacy classes
Size | Order | Action on
$ r_{ 1 }, r_{ 2 } $
| Character value |
$1$ | $1$ | $()$ | $1$ |
$1$ | $2$ | $(1,2)$ | $-1$ |
