We use a polyhedral criterion for the existence of diagonal splittings to investigate which toric varietiesare diagonally split. Our results are stated in terms of the vector configuration given by primitive generators of the 1-dimensional cones in the fan defining. We show, in particular, thatis diagonally split at allif and only if this configuration is unimodular, and thatis not diagonally split at anyif this configuration is not-regular. We also study implications for the possibilities for the set ofat which a toric varietyis diagonally split. References
