Basic procedures for Cyclic, Hamming, Binary Reed-Muller, BCH, Golay codes  The parity check matrix of the binary Hamming code is related to the generator matrix of the 1st order Reed-Muller code. Also, the (12,6)-Golay code and the (24,12)-Golay codes are also included We give a program which returns all the...
