Abstract: We study perfect codes in the homogeneous metric over the ring $\mathbb {Z}_{{2}^k}, k\ge 2$ . We derive arithmetic nonexistence results from Diophantine equations on the parameters resulting from the sphere packing conditions, and a…

Abstract: Motivated by applications to DNA-storage, flash memory, and magnetic recording, we study perfect burst-correcting codes for the limited-magnitude error channel. These codes are lattices that tile the integer grid with the appropriate error ball. We…

Abstract: A code is said to be propelinear if its automorphism group contains a subgroup acting on its codewords regularly. A subgroup of the group $$GA(r,q)$$ of affine transformations is said to be regular if it acts…

Abstract: In this paper, we focus on the perfect and total perfect codes of the non-coprime and coprime graphs associated to the dihedral groups and finite Abelian groups. We used the advantage of independent sets and…
