Abstract :
The linear inequality method for covering codes is used to improve the lower bounds of t[n, k], the smallest covering radius of any [n, k] binary linear code. To make better use of the strength of this method, the relation between the covering radius of a code and the minimum distance of its dual code is studied. The authors obtained 65 improved lower bounds for t[ n, k] within the range of n⩽64
