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
