nauty-vcolg \- colour the vertices of graphs in all distinct ways
.SH SYNOPSIS
.B vcolg
[\fI\,-q\/\fR] [\fI\,-u|-T|-o\/\fR] [\fI\,-e#|-e#:#\/\fR] [\fI\,-m#\/\fR] [\fI\,-c#,\/\fR..\fI\,,#\/\fR] [\fI\,-f#\/\fR] [\fI\,infile \/\fR[\fI\,outfile\/\fR]]
.SH DESCRIPTION
.IP
Read graphs or digraphs and colour their vertices 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.
.TP
\fB\-e\fR# | \fB\-e\fR#:#
specify a value or range of the total value of the colours
.HP
\fB\-m\fR# number of available colours (default 2 if \fB\-c\fR not given)
.TP
\fB\-c\fR#,..,#
specify the maximum number of vertices of each colour
.IP
The total must at least equal the number of vertices in the input.
.TP
\fB\-d\fR#,..,#
minimum vertex degree for each colour (out\-degree for digraphs)
.TP
\fB\-D\fR#,..,#
maximum vertex degree for each colour (out\-degree for digraphs)
.HP
\fB\-d\fR and \fB\-D\fR can have fewer colours than \fB\-m\fR/\-c but not more
.HP
\fB\-f\fR# Use the group that fixes the first # vertices setwise
.TP
\fB\-T\fR
Use a simple text output format (nv ne {col} {v1 v2})
.TP
\fB\-o\fR
Use sparse6 (undirected) or digraph6 (directed) for output,
.IP
provided m=2 and the inputs have no loops.
.TP
\fB\-u\fR
no output, just count them
.TP
\fB\-q\fR
suppress auxiliary information
