Hamming code

An errordetecting and errorcorrecting binary code, used in data transmission, that can (a) detect all single and doublebit errors and (b) correct all singlebit errors. Note: A Hamming code satisfies the relation 2^{m} n+1, where n is the total number of bits in the block, k is the number of information bits in the block, and m is the number of check bits in the block, where m = n  k.
