Is it not possible to represent this in a 2D graph for learning purposes? Or is that the point, that it can't be represented in 2D? I'm imaging square nodes with 0 or 1 in them, and 8 other 0 or 1's on the corner and edges, denoting the parity of other nodes, and by simply inspecting these edge/corner bits you can tell whether the whole graph is corrupted?
