**This web page contains auxiliary information** for the article *Polytopes Derived from Sporadic Simple Groups*,
to appear in *Contributions To Discrete Mathematics*.

In particular, the generators of the automorphism groups of every polytope discovered
are stored in the file sporpolys.tgz (6.7 Mb, uncompresses to 18 Mb),
as permutations. These may be read into GAP
via the command

issued from the folder into which sporpolys.tgz is unzipped.

I also provide links to tables summarising the polytopes for each group.
