data (lrs)

This page contains data to define the Chan-Robbins-Yuen polytopes in type D and C in the lrs package

Requirements

• install lrs package

The following text files have the vertex description of polytopes isomorphic to CRYDn and CRYCn for n= 6, 7, 8 ,9. You can use lrs to find calculate their volumes.

• download a text file, for example vertcryD6.ext and run lrs vertcryD6.ext (to get the normalized volume multiply the result by dimension!)
