perm            > readshare(perm, combinat); (50K)
                SEE ALSO: combinat/perm.tex  (30K)
                A package of routines for computing with permutation groups,
                including routines for computing orbits, subgroups, testing
                for conjugacy. There are also procedures used to represent and
                manipulate combinatorial structures.

posets          > readshare(posets, combinat); (58K)
                SEE ALSO: combinat/posets.tex
                A package of routines for manipulating partially ordered sets
                including routines to enumerate all non-isomorphic Posets and
                Lattices on n vertices.

SF              > readshare(SF, combinat); (37K)
                SEE ALSO: combinat/SF.tex
                A package of routines for manipulating symmetric functions.
                The package can express the symmetric functions in the bases
                (1) the monomial symmetric functions
                (2) the elementary symmetric functions
                (3) the complete homogeneous symmetric functions
                (4) the power sum symmetric functions
                (5) the Schur functions

relpoly         > readshare(relpoly, combinat);
relpoly.ms      SEE ALSO: combinat/relpoly.ms
                The function relpoly(G,p) computes the all terminal
                reliability polynomial for a graph G with probability
                of edge failure p.

symmpoly        > readshare(symmpoly, combinat);
                Utility routine for generating the symmetric polynomials.

coxeter         > readshare(coxeter, coxeter); (112K)
weyl            > readshare(weyl, coxeter);
                SEE ALSO: coxeter/examples, coxeter/coxeter.tex

                The coxeter package contains 30 basic procedures for studying
                roots systems and finite Coxeter groups.  The weyl package is a
                supplement to the coxeter package that contains 7 procedures
                for manipulating weight vectors and computing multiplicities
                for irreducible representations of semisimple Lie algebras.
