Abstract
A modified lower bound for binary codes with covering radius one is derived. Let K q(n ,R ) denote the minimum cardinality of a q -ary code with covering radius R . The new bound shows that K 2(11,1)⩾177 and that K 2(17,1)⩾7391, improvements of the best lower bounds known. The authors also generalize a known lower bound for binary codes to the case of arbitrary q . For q =3, this simple bound improves the best lower bounds known in several cases. An updated version of a table for K 3(n ,R ) is included
