I'm currently studying polytopes and using the book Lectures in Geometric Combinatorics by Thomas. When I come to Schlegel diagrams, I do not quite understand how to determine whether a Schlegel diagram is a Schlegel diagram. In the book on p. 34, it states that if $\mathcal{D}$ is indeed a Schlegel diagram, then $\mathcal{D}$ is a regular subdivision of $|\mathcal{D}|$, the support of $\mathcal{D}$. Can anyone help me with this?
