+  Error-detecting six-qubit code with rate \(2/3\) whose codewords are cat/GHz states.
   A set of stabilizer generators is \(XXXXXX\) and \(ZZZZZZ\).
   It is the unique code for its parameters, up to local equivalence \cite[Tab. III]{arxiv:quant-ph/9608006v5}.
   Concatenations of this code with itself yield the \([[6^r,4^r,2^r]]\) level-\(r\) \textit{many-hypercube} code \cite{arxiv:2403.16054}.
