  By using first-principles calculations, we propose that WC-type ZrTe is a new
type of topological semimetal (TSM). It has six pairs of chiral Weyl nodes in
its first Brillouin zone, but it is distinguished from other existing TSMs by
having additional two paris of massless fermions with triply degenerate nodal
points as proposed in the isostructural compounds TaN and NbN. The mirror
symmetry, three-fold rotational symmetry and time-reversal symmetry require all
of the Weyl nodes to have the same velocity vectors and locate at the same
energy level. The Fermi arcs on different surfaces are shown, which may be
measured by future experiments. It demonstrates that the "material universe"
can support more intriguing particles simultaneously.
