NAME
nauty-vcolg - colour the vertices of graphs in all distinct ways
SYNOPSIS
vcolg [-q] [-u|-T|-G|-A|-B] [-e#|-e#:#] [-m#] [-f#] [-D#|-r#|-l#] [infile [outfile]]
DESCRIPTION
Read undirected loop-free graphs and colour their vertices in
in all possible ways with colours 0,1,2,... . Isomorphic graphs derived from the same input are
suppressed. If the input graphs are non-isomorphic then the output graphs are also.
-e# | -e#:#
specify a value or range of the total value of the colours
-m# number of available colours (default 2)
-f# Use the group that fixes the first # vertices setwise
-T use a simple text output format (nv ne {col} {v1 v2})
-u no output, just count them
-q suppress auxiliary information
