Large sets of wrapped Hamilton cycle decompositions of complete tripartite graphs

We also investigate the existence of wrapped Hamilton cycle decompositions of the λ-fold complete 3-uniform tripartite hypergraph λKn,n,n(3) which have the additional property that they can themselves be partitioned into WHDs (a result reminiscent of partitioning Steiner Quadruple Systems into BIBDs with block size 4).
