These are the instructions to load the Coxeter program. The program source code is contained in the following 15 files bruhat.c bruhat.h commands.c commands.h globals.h interface.c interface.h kl.c kl.h main.c main.h memory.c types.h weyl.c weyl.h In addition to these, there is a makefile, and the README you are currently reading. If you wish to download the files through ftp, just create a directory on your local machine to store them, move to that directory, ftp to this host and say "mget *" . After the files are succesfully downloaded, it is enough to say "make". This should compile the files and create an executable program called "coxeter". Compiler messages, if any, should be of the harmless sort. It is then enough to say "coxeter" to run the program. When Kazhdan-Lusztig polynomials are computed for group Xn, three files are created, named Xn.list, Xn.store, Xn.zone. These contain the results of the computation in condensed form. They may be useful for later searching or other processing, and they are used to avoid recomputation if the same group is used again; but they may be deleted if desired.
