Extending the Concept of Decomposability for Triple Systems

A triple system of order ν and index λ is MPT-decomposable if it contains λ pairwise disjoint maximum packings of triples (MPT) of order ν, and it is MPT-free if it contains no MPT of order ν. We determine completely the spectrum for MPT-decomposable, as well as for MPT-indecomposable triple systems, and obtain partial results concerning the spectrum of MPT-free triple systems.
