Abstract

It is shown that the necessary conditions are sufficient for the existence of all \(c\)-BRDs\((v, 3, \lambda)\) for negative \(c\)-values. This completes the study of \(c\)-BRDs with block size three as previously the authors and J. Seberry have shown that the necessary conditions are sufficient for \(c \geq -1\).
