The author proves analogues of the McEliece and Tietäväinen bounds for constant weight codes by deriving inequalities for the mean of \(S(x,y)^ r\), where S(x,y) a matrix whose entries are constant over a family of binary relations forming an n-class coloring structure, which is positive semidefinite.
