Topcom is mathematical software written by Jorg Rambau for computing and manipulating triangulations of polytopes and chirotopes.
This Macaulay2 package provides an interface for some of the functionality of this software.
The package is meant as an internal package, to be called by packages such as Polyhedra. It is highly recommended to use those packages, rather than calling this package directly.
The chirotope of a point set (or vector set), consisting of the columns of the $d \times n$ matrix $A$, is the function which assigns to each $d+1 \times d+1$ minor of $\overline{A}$ the sign of its determinant. Topcom encodes this into a string. See chirotopeString for details about the output of this function.
This documentation describes version 0.95 of Topcom.
