31. Early codes were typically compilations of phrases and corresponding codewords numbering in the tens of thousands. 32. We have q ^ k codewords . 33. The codewords in the perfect ( non-extended ) binary Golay code are of size 23. 34. The codewords are represented by patterns of dark ( bar ) and light ( space ) regions. 35. The book also uses codewords to record certain events that happen in the course of the book. 36. However the actual choice of mapping has a strong influence on the secondary structure of the codewords . 37. But the actual list of close-by codewords is only a small set within that subspace. 38. The codewords of this cyclic code are all the polynomials that are divisible by this generator polynomial. 39. Now, suppose that every two codewords differ by more than a burst of length \ ell. 40. Now, suppose that every two codewords differ by more than two bursts of length \ ell.
