   The qubit connectivity graph is not quite a 2D grid and is instead decomposable into two planar subgraphs of degree three; there exists an optimized layout minimizing Euclidean communication distance for check operators \cite{arxiv:2404.18809}.
   There are \(n\) \(X\) and \(Z\) check operators, with each one of weight six.
