This is the command nauty-directg that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
nauty-directg - generate small digraphs with given underlying graph
SYNOPSIS
directg [-q] [-u|-T|-G] [-V] [-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.
-V only output graphs with nontrivial groups (including exchange of
isolated vertices).
The -f option is respected.
-u no output, just count them
-q suppress auxiliary information
