Abstract
As a part of the author’s series study on the constant weight codes
we have initially found the structure properties and the equivalent classes for the unextendable binary codes of constant weight and distance with parameters (n
2
m) and (n
4
m) in this paper.A few open problems about the structure of (n
2k
m) codes with constant weight and distance for k≥3 are also proposed
