Abstract

A code \(C\subseteq {Z^{n}_{2}}\) , where Z 2 =  {0,1}, is said to be a binary μ-fold R-covering code, if for any word \(v \in Z^n_2\) there are at least μ distinct codewords \(c \in C\) which differ from v in at most R coordinates. The size of the smallest binary μ-fold R-covering code of length n is denoted by K(n, R, μ). In this paper we use integer programming and exhaustive search to improve 57 lower bounds on K(n, R, μ) for 6 ≤ n ≤ 16, 1 ≤ R ≤ 4 and 2 ≤ μ ≤ 4.
