nauty - 2.8.6+ds-2 main

nauty (No AUTomorphisms, Yes?) is a set of procedures for computing
automorphism groups of graphs and digraphs. This mathematical software
suite is developed by Brendan McKay and Adolfo Piperno:
http://pallini.di.uniroma1.it
.
nauty computes graph information in the form of a set of generators,
the size of the group, and the orbits of the group; it can also
produce a canonical label. The nauty suite is written in C and comes
with a command-line interface, a collection of command-line tools,
and an Application Programming Interface (API).
.
This package provides the nauty interface named dreadnaut, and a
small collection of utilities called gtools.
