Quaternary linear code over \(\mathbb{Z}_4\)

Description

A linear code encoding \(K\) states (codewords) in \(n\) coordinates over the ring \(\mathbb{Z}_4\) of integers modulo 4.

Notes

Code Database, including quasi-cyclic and quasi-twisted codes [1].

Cousins

  • Melas code— The even-weight subcode of the Melas code can be lifted to a code over \(\mathbb{Z}_4\) [2].
  • Hergert code— Hergert codes can be seen, via the Gray map, as linear codes over \(\mathbb{Z}_4\) [3,4].
  • Delsarte-Goethals (DG) code— DG codes can be seen, via the Gray map, as extended linear cyclic codes over \(\mathbb{Z}_4\) [3,4].
  • Reed-Muller (RM) code— RM codes are images of linear quaternary codes over \(\mathbb{Z}_4\) under the Gray map [5; Sec. 6.3].
