Abstract :
A series of explicit low-rate binary linear codes that have relatively low covering radius and can be rapidly decoded is exhibited. These codes can be derived from higher-dimensional analogs of the Gale-Berlekamp switching game. Conjectures of independent interest involving Hadamard matrices are given that could yield semiexplicit covering codes of very low density
