Includes several applications: hopfviewer (viewing the Clifford torus), topeviewer (viewing 4D polytopes), and examples of user-defined parametric surfaces in 3D and 4D.

This paper is the basis for esve.
Find the automorphism group of a directed graph (possibly with colored vertices and arcs).
Find the symmetry group of a set of points in n-dimensional space. The permutation representation and the matrix representation are both available, including the eigenvalues and eigenvectors of each element.
Written in C++ with optional bindings to the ruby language.
symfind-1.0.3 download
symfind-1.0.3 documentation
Eigenvalues, eigenvectors, QR decomposition, singular value decomposition, etc.
Includes bindings to the LAPACK library.
This package is required for the spacegroup ruby script found in symfind.
Includes a description of each configuration's symmetry group (produced by symfind).
These may be viewed with topeviewer.
Includes a comprehensive test of general Dickson algebra identities as well as octonion and quaternion identities.
