Groups & Graphs is a software package for graphs and
their automorphism groups. It runs on a MacIntosh
platform, and is available via anonymous ftp from
ftp.cc.umanitoba.ca in the directory /pub/mac
The current version is 2.1. A new version (2.2) will soon
be released. Contact: bkocay@cs.umanitoba.ca

I haven't yet got a chance to ftp the code and install it
here on our machine.

Luck,
Nishit
