  Topological materials have been a main focus of studies in the past decade
due to their protected properties that can be exploited for the fabrication of
new devices. Among them, Weyl semimetals are a class of topological semimetals
with non-trivial linear band crossing close to the Fermi level. The existence
of such crossings requires the breaking of either time-reversal or inversion
symmetry and is responsible for the exotic physical properties. In this work we
identify the full-Heusler compound InMnTi$_2$, as a promising, easy to
synthesize, $T$- and $I$-breaking Weyl semimetal. To correctly capture the
nature of the magnetic state, we employed a novel $\mathrm{DFT}+U$
computational setup where all the Hubbard parameters are evaluated from
first-principles; thus preserving a genuinely predictive \textit{ab initio}
character of the theory. We demonstrate that this material exhibits several
features that are comparatively more intriguing with respect to other known
Weyl semimetals: the distance between two neighboring nodes is large enough to
observe a wide range of linear dispersions in the bands, and only one kind of
such node's pairs is present in the Brillouin zone. We also show the presence
of Fermi arcs stable across a wide range of chemical potentials. Finally, the
lack of contributions from trivial points to the low-energy properties makes
the materials a promising candidate for practical devices.
