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 ...
