Hi,

could you verify my solution? I want the determinant of the following and I got 0 wich I wouldn't expect. Dou you get this to?

$\displaystyle A \in M_{4}(\mathbb{F}_{3})$

$\displaystyle A = \begin{pmatrix} 0 & 1 & 1 & 2 \\ 2 & 0 & 1 & 1 \\ 2 & 2 & 0 & 1 \\ 1 & 2 & 2 & 0 \end{pmatrix}$

$\displaystyle det(A)=0$ in my solution

thanks

greetings
