We prove that for every prime $p$ there exists a $(0,1)$-matrix

$M$ of size $t_p(n,m)\times n$ where

$$t_p(n,m)=O\left(m+\frac{m\log \frac{n}{m}}{\log \min({m,p})}\right)$$ such that every

$m$ columns of $M$ are linearly independent over $\Z_p$, the field

of integers modulo $p$ (and therefore over any field of

characteristic $p$ and over the real ...
