directg(1)
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
