Tetracode[1]
Description
The \([4,2,3]_{GF(3)}\) self-dual MDS code with generator matrix \begin{align} \begin{pmatrix}1 & 0 & 1 & 1\\ 0 & 1 & 1 & 2 \end{pmatrix}~, \tag*{(1)}\end{align} where \(GF(3) = \{0,1,2\}\). Has connections to lattices [1].
Notes
See corresponding MinT database entry [2].
Parents
- Simplex code — The tetracode is equivalent to \(S(3,2)\).
- \(q\)-ary Hamming code — The tetracode is equivalent to the \(r=2\) \(3\)-ary Hamming code.
- Maximum distance separable (MDS) code
- Extended GRS code — The tetracode is an extended RS code [1; pg. 81]
Cousins
- Dual linear code — The tetracode is self-dual.
- Ternary Golay code — Extended ternary Golay codewords can be obtained from tetracodewords [1]. The tetracode can be used to decode the extended ternary Golay code [3].
