PermGroup: A Mathematica Package for Permutation Groups, Group Actions and Polya TheoryPermGroup is a Mathematica package dealing with permutation groups, group actions and Polya theory. The package has been developed by Thomas Bayer, a former student of the RISC Combinatorics group.
Registration and Legal Notices The source code for this package is password protected. To get the password send an email to Peter Paule.

A Note on Encoded Files This package contains one or more Mathematica input files which are encoded. Those files cannot be read or modified directly as plain text, but can be loaded into Mathematica just like any normal input file (i.e., with <<"file" or Get["file"]). There is no need (and also no way) to decode them by using additional software or a special key.If loading an encoded file causes a syntax error, open it with a text editor and remove any blank lines at the beginning (for some reason your Mac could have inserted them silently...).
The Package The PermGroup package consists of the Mathematica input files a short ASCII-documentation and the manual in form of Mathematica 3.0 notebooks Alternatively, you can download the whole package as a compressed archive file
Important Upgrade Information Beginning with version 1.2 the function Element has been renamed to PGElement for compatibility with recent versions of Mathematica.
Versions and Bugs The current version of the package is 1.2 last updated on June 21, 2004.
