Embeddings of Maximum Packings of Triples

Abstract

Let \(\operatorname{MPT}(v,\lambda)\) denote a maximum packing of triples of order \(v\) with index \(\lambda\). For \(\lambda > 1\) and \(v \geq 3\), it is proved in this paper that the necessary and sufficient condition for the embedding of an \(\operatorname{MPT}(v,\lambda)\) in an \(\operatorname{MPT}(u,\lambda)\) is \(u \geq 20v + 1\).
