# CTAN has a new package: PST-Cox

We have wrote a new package for PSTricks for drawing 2 dimensional projection of complex regular polyopes (after the work of Coxeter). The package consists in a library of macro for drawing the projections. The complex polytopes appears in the study of the roots systems and play a crucial role in many domains related to mathematics and physics. These polytopes have been completely described by Coxeter in his book "Regular Complex Polytopes". there exist only a finite numbers of exceptional regular complex polytopes (for example the ikos\ae dron) and some infinite series (for example, one can construct multi-dimensional analogous of the hypercube in any -finite- dimension). The library contains two packages. The first, pst-coxcoor, is devoted to the exceptional complex regular polytopes whose coordinates have been pre-computed. The second, pst-coxeterp, is devoted to the infinite series. One can find also other informations in the beautiful page of Jean-Michel Sarlat: http://melusine.eu.org/syracuse/pstricks/pst-cox/ To contact me, use the email given in the documentation of the package. best wishes Jean-gabriel Luque

This package is located at http://tug.ctan.org/tex-archive/graphics/pstricks/contrib/pst-cox . More information is at http://tug.ctan.org/pkg/pst-cox (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org .

## pst-cox – Drawing regular complex polytopes with PSTricks

Pst-cox is a PSTricks package for drawing 2-dimensional projections of complex regular polytopes (after the work of Coxeter).

The package consists of a macro library for drawing the projections. The complex polytopes appear in the study of the root systems and play a crucial role in many domains related to mathematics and physics. These polytopes have been completely described by Coxeter in his book “Regular Complex Polytopes”.

There exist only a finite numbers of exceptional regular complex polytopes
(for example the icosahedron) and some infinite series (for example,
one can construct a multi-dimensional analogue of the hypercube in
any *finite* dimension).

The library contains two packages. The first, pst-coxcoor, is devoted to the exceptional complex regular polytopes whose coordinates have been pre-computed. The second, pst-coxeterp, is devoted to the infinite series.
