2D parity code error detection/correction?
With this kind of parity only a single bit error can be corrected. So not a single error can be corrected in this example.

Here one column and three rows contain an error. To rows could be corrected by flipping two bits in any arbitrary row (where they intersect with the two rows that contain an error), it wouldn't change their parity bit. The remaining error could be fixed at the intersection of the row and column with the remaining error.

However, since the choice of the first column is arbitrary, the errors cannot be corrected.
