NAUTY-SHOWG

NAME

nauty-showg − display graphs in a variety of forms (stand-alone subset of listg)

SYNOPSIS

showg [−p#:#l#o#Ftq] [−a|−A|−c|−d|−e] [infile [outfile]]

DESCRIPTION

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.
