### G1, G2, H1, H2 are submatrices of the generator and parity check matrices of a code as described below. Can G1 * H2' and G2 * H1' both be all zeroes?

$G$ and $H$ are the generator and parity check matrices respectively of a linear block code. Let $G_1 = G(:, 1:n-s)$ (Matlab style representation of sub matrices). That is, $G_1$ is equal to ...
