Abstract :
A binary extended 1-perfect code of length n + 1 = 2t is additive if it is a subgroup of Z2α × Z4β. The punctured code by deleting a Z2 coordinate (if there is one) gives a perfect additive code. 1-perfect additive codes were completely characterized and by using that characterization we compute the possible parameters α, β, rank, and dimension of the kernel for extended 1-perfect additive codes. A very special case is that of extended 1-perfect Z4-linear codes.
