  Triple gauge boson hadroproduction, in particular the production of three
$W$-bosons at the LHC, is considered at next-to leading order accuracy in QCD.
The NLO matrix elements are combined with parton showers. Multijet merging is
invoked such that NLO matrix elements with one additional jet are also
included. The studies here incorporate both the signal and all relevant
backgrounds for $VH$ production with the subsequent decay of the Higgs boson
into $W$-- or $\tau$--\-pairs. They have been performed using \SherpaOpenLoops
in combination with Collier.
