Let $G_1, G_2, G_3$, be valid generator matrices of dimensions $\mathbb F^{k_i imes n_i}$, all over the same field $\mathbb F$. Recall that ``valid'' means that for all $i$, $k_i \leq n_i$ and $ ext{rank}(G_i) = k_i$. True or false: Assuming $k_1 = k_2 + k_3$, the matrix $egin{pmatrix} G_1 &\vline &egin{matrix} G_2 &\vline &0\ \cline{1-3} 0 &\vline &G_3 \end{matrix} \end{pmatrix}$ is also a valid generator matrix.
