Abstract : We obtain a necessary and sufficient condition for the existence of Mendelsohn triple systems excluding contiguous units with $\lambda=1$. Also, we obtain the spectrum for cyclic such systems.
Keywords : triple system sampling plan excluding contiguous units, directed (Mendelsohn) triple system, automorphism, (partial) triple system, Latin square, group divisible design
