This is Version 1.0.0 of the package mfer written for GAP 4, whose aim is to provide access to the classification of the endomorphism rings of the multiplicity-free permutation modules of the sporadic simple groups and their cyclic and bicyclic extensions.
Part of the data is available not only in GAP 4 but also in the web. This holds for the permutation characters and the character tables of the endomorphism rings as well as for the bibliography collected from earlier publications on this topic.
There is a manual (available in HTML and pdf format) that describes the available functions in detail.
The package requires GAP 4.4.10 (or a newer version of GAP).
The data have been computed by various people, see the manual section "Sources of the Data" for details.
The GAP functions were written by Thomas Breuer, Ines Höhler, and Jürgen Müller.
If you have used the mfer package to solve a problem then please send a short email to Thomas Breuer or Jürgen Müller about it.
Any comments about the package are very welcome. If you have found important features missing or if there is a bug, let us know and we will try to address it in the next version of the package.
If you want to get Version 1.0.0 of the mfer package then download the most appropriate of a gzipped tar archive or a zoo archive. Further information is contained in the README file.
(The README file and the archives are available also on the GAP servers.)
