  We show that the cubic compound PtBi2, is a topological semimetal hosting a
sixfold band touching point in close proximity to the Fermi level. Using
angle-resolved photoemission spectroscopy, we map the bandstructure of the
system, which is in good agreement with results from density functional theory.
Further, by employing a low energy effective Hamiltonian valid close to the
crossing point, we study the effect of a magnetic field on the sixfold fermion.
The latter splits into a total of twenty Weyl cones for a Zeeman field oriented
in the diagonal, [111] direction. Our results mark cubic PtBi2, as an ideal
candidate to study the transport properties of gapless topological systems
beyond Dirac and Weyl semimetals.
