One way of detecting errors is to transmit data as a block of n rows of k bits per row and add parity bits to each row and each column. The bitin the lower-right corner is a parity bit that checks its row and its column. Will this scheme detect all single errors? Double errors? Triple errors? Show that this scheme cannot detect some four-bit errors.
