In this paper, we present various results concerning (r. <= l)-identifying codes in the Hamming space F(n). First we concentrate on Improving the lower bounds on (r. <= 1)-identifying codes for r > 1 Then we proceed by introducing new lower hounds on (r. <= l)-identifying codes with l >= 2 We also prove that (r, <= l)-identifying codes can be constructed frorn known ones using a suitable direct sum when l > 2 Constructions for (r. <= 2)-identifying codes with the best known cardinalities are also given (C) 2009 Elsevier Ltd All rights reserved.
