Secondary polytope of the perturbed "mother of all examples".
This point configuration arises by slightly perturbing the "mother of all examples". The two non-regular triangulations of the original configuration now separate, one of them becoming regular in the process. The other one moves into the interior of the secondary polytope.
The file pmother.sec.poly contains all triangulations of this point configuration and its flip graph. This graph is also provided in gml format in the file pmother.sec.gml .
