A simple construction of cover-free $(s,\ell)$-code with certain constant weight (1605.06847v1)

Abstract: We give a method of constructing a cover-free $(s, \ell)$-code. For $k > s$, our construction yields a $ {{n \choose s} \choose \ell}\times {n \choose k}$ cover-free $(s, \ell)$-code with a constant column weight.
