Secondary polytope of the twisted capped prism.
The twisted capped prism is constructed by twisting a triangular prism, taking the convex hull, and adding a pyramid of the right height on top. This polytope has 26 triangulations, of which the single non-regular one is marked in red in the flip-graph. This non-regular triangulation lies in the interior of the secondary polytope.
This example was constructed by Carl W. Lee and Peter Kleinschmidt in .
The file twcap.sec.poly contains all triangulations of the twisted capped prism and its flip graph. This graph is also provided in gml format in the file twcap.sec.gml .
