Abstract
A subspace C of the binary Hamming space F (n) of length n is called a linear r-identifying code if for all vectors of F (n) the intersections of C and closed r-radius neighbourhoods are nonempty and different. In this paper, we give lower bounds for such linear codes. For radius r = 2, we give some general constructions. We give many (optimal) constructions which were found by a computer search. New constructions improve some previously known upper bounds for r-identifying codes in the case where linearity is not assumed.
