nauty-showg − display graphs in a variety of forms (stand-alone subset of listg)
showg [−p#:#l#o#Ftq] [−a|−A|−c|−d|−e] [infile [outfile]]
Write graphs in human−readable format.
infile is the input file in graph6 or sparse6 format outfile is the output file Defaults are standard input and standard output.
−p#, −p#:#, −p#−# : only display one graph or a sequence of |
graphs.
The first graph is number 1. A second number
which is empty or zero means infinity.
−a |
: write the adjacency matrix |
||
−A |
: same as −a with a space between entries |
||
−d |
: write output to satisfy dreadnaut |
||
−c |
: write compact dreadnaut form with minimal line−breaks |
||
−e |
: write a list of edges, preceded by the order and the |
number of edges
−o# : specify number of first vertex (default is 0) |
||
−t |
: write upper triangle only (affects −a, −A, −d and default)
−F |
: write a form−feed after each graph except the last |
||
−l# : |
specify screen width limit (default 78, 0 means no limit)
This is not currently implemented with −a or −A.
−q |
|||
: suppress auxiliary output |
|||
−a, −A, |
−c, −d and −e are incompatible.
