Description: Codes Over ℤ₄ is a package that expand the current functionality for codes over ℤ₄ in Magma. Specifically, there are functions which give new constructions for some families of codes over ℤ₄ and constructions to obtain new codes over ℤ₄ from given codes over ℤ₄. Moreover, efficient functions for computing the rank and dimension of the kernel of any code over ℤ₄ are also include, as well as general functions to compute the coset leaders for a subcode in a code over ℤ₄. Finally, there are also functions to compute the permutation automorphism group for Hadamard and extended perfect codes over ℤ₄, and their cardinal.
