\([4,2,3]_4\) RS\(_4\) code

Alternative names: \(XQ(\mathbb{F}_4,3)\).

Description

A Type II Euclidean self-dual extended RS code that is the smallest quaternary extended QR code [1; pg. 296][2; Sec. 2.4.2].

A generator matrix for the code is \begin{align} \begin{pmatrix} 1 & 1 & 1 & 1 \\ 0 & 1 & \omega & \omega^2 \end{pmatrix}~, \tag*{(1)}\end{align} where \(\mathbb{F}_4 = \{0,1,\omega, \bar{\omega}\}\) is the quaternary Galois field.

The automorphism group of the code is \(3.S_4\) [2; Sec. 2.4.2].
