Description
The 1-skeleton of a convex polytope $P$ is called the graph of $P$.
A graph of a simplicial $d$-polytope is said to be toric colorable if there is a vertex coloring $\lambda \colon V(G) \to \mathbb{Z}^d$ such that $\{v_1, \ldots, v_d\}$ forms a face of $P$ implies that $\{\lambda(v_1), \ldots, \lambda(v_d)\}$ is unimodular.
In this talk, we discuss the toric colorability of graphs of simplicial $d$-polytopes with $d+4$ vertices.
