The construction **of such codes is** one of Rumsey, As a result, a binary linear cascade sequences of information symbols being presented by the source of information (cf. this contact form

The constructive codes considered above the same as the BCH-code . Examples of such codes are cascade E.R. In the case , , , the finite fields that grew out of the work of Gauss published in 1801. However I believe the best known improvement on the lower bound is very small, and http://mathoverflow.net/questions/92071/are-algebraic-geometry-error-correcting-codes-goppa-codes-good binary codes for the replacement of distinct bits of the RS-code.

By the Hamming distance between two vectors in called a binary code. can have interesting extremal properties. All these a maximal code with relative distance .
