NAME
directg - Read undirected graphs and orient their edges in all possible
ways.
SYNOPSIS
directg [-q] [-u|-T|-G] [-o] [-f#] [-e#|-e#:#] [infile [outfile]]
DESCRIPTION
Read undirected graphs and orient their edges in all possible
ways.
Edges can be oriented in either or both directions (3
possibilities). Isomorphic directed 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 number of arcs
-o orient each edge in only one direction, never both
-f# Use only the subgroup that fixes the first # vertices setwise
-T use a simple text output format (nv ne edges) instead of
digraph6
-G like -T but includes group size as third item (if less than
10^10)
The group size does not include exchange of isolated vertices.
-u no output, just count them
-q suppress auxiliary information
