Basedon the concept of unextendable code with constant weight and distance given in paper [1], we use design Principle Of the window matrix for constant weight and distance codes, so that the structure of unextendable code with constant weight and distance for (n,4,m) are analysed once analysed once again. At the same time,a few peculiar structure type;basic ease, symmetrical cased and nonsymmetrical cased in weight of code are discussed,We have combined the structure problem of different equivalent classes of unextendable code with constant weight and distance with Parameters (n,4,m) in this paper.
