### Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 7.
Roots:
 $r_{ 1 }$ $=$ $$2 + 20\cdot 31 + 9\cdot 31^{2} + 25\cdot 31^{3} + 3\cdot 31^{4} + 20\cdot 31^{5} + 12\cdot 31^{6} +O(31^{7})$$ $r_{ 2 }$ $=$ $$4 + 21\cdot 31 + 25\cdot 31^{2} + 20\cdot 31^{3} + 26\cdot 31^{4} + 14\cdot 31^{5} + 15\cdot 31^{6} +O(31^{7})$$ $r_{ 3 }$ $=$ $$7 + 2\cdot 31 + 25\cdot 31^{2} + 17\cdot 31^{3} + 14\cdot 31^{4} + 23\cdot 31^{5} + 8\cdot 31^{6} +O(31^{7})$$ $r_{ 4 }$ $=$ $$8 + 3\cdot 31^{2} + 11\cdot 31^{3} + 30\cdot 31^{4} + 19\cdot 31^{5} + 6\cdot 31^{6} +O(31^{7})$$ $r_{ 5 }$ $=$ $$23 + 30\cdot 31 + 27\cdot 31^{2} + 19\cdot 31^{3} + 11\cdot 31^{5} + 24\cdot 31^{6} +O(31^{7})$$ $r_{ 6 }$ $=$ $$24 + 28\cdot 31 + 5\cdot 31^{2} + 13\cdot 31^{3} + 16\cdot 31^{4} + 7\cdot 31^{5} + 22\cdot 31^{6} +O(31^{7})$$ $r_{ 7 }$ $=$ $$27 + 9\cdot 31 + 5\cdot 31^{2} + 10\cdot 31^{3} + 4\cdot 31^{4} + 16\cdot 31^{5} + 15\cdot 31^{6} +O(31^{7})$$ $r_{ 8 }$ $=$ $$29 + 10\cdot 31 + 21\cdot 31^{2} + 5\cdot 31^{3} + 27\cdot 31^{4} + 10\cdot 31^{5} + 18\cdot 31^{6} +O(31^{7})$$
