*Solve algebraic, geometric, combinatorial problems on linear spaces*

**Branch:** CURRENT,

**Version: **1.6.9,

**Package name:** 4ti2-1.6.9,

**Maintainer: **kamelderouiche4ti2 is a software package for algebraic, geometric and combinatorial problems

on linear spaces. It computes

* the circuits of a cone

* a problem matrix corresponding to graphical statistical models

* generators for the symmetry group acting on 4-way tables

* the Graver basis of a matrix or a given lattice

* a Groebner basis of the toric ideal of a matrix or, more general, of the

lattice ideal of a lattice

* a Markov basis (generating set) of the toric ideal

* the minimal solution of an integer linear program or, more general, a lattice

program, using a Groebner basis

* the normal form of a list of feasible points

* the primitive partition identities, that is, the Graver basis of [1 2 3 ... N]

* a generator description of a cone

* the extreme rays of a cone

* the minimal solution of an integer linear program or, more general, a lattice

program using a Groebner basis

* an integer lattice basis

* solutions of linear inequality and equation systems over the integers
