Linear Size Optimal q-ary Constant-Weight Codes and Constant-Composition Codes
An optimal constant-composition or constant-weight code of weight w has linear size if and only if its distance d is at

The PBD-Closure of Constant-Composition Codes
—We show an interesting pairwise balanced design (PBD)-closure result for the set of lengths of constant-composition codes whose distance and size meet certain conditions. A cons...

Equidistant frequency permutation arrays and related constant composition codes
This paper introduces and studies the notion of an equidistant frequency permutation array (EFPA). An EFPA of length n = m, distance d and size v is defined to be a v
