NAME¶

nauty-listg - display graphs in a variety of forms

SYNOPSIS¶

listg [-fp#:#l#o#Ftq] [-a|-A|-c|-d|-e|-H|-M|-W|-L|S|-s|-b|-G|-y|-Yxxx]

DESCRIPTION¶

[infile [outfile]]

Write graphs in human-readable format.

-f

: assume inputs have same size (only used from a file

and only if -p is given)

-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. This option won't work for incremental input.

-a

: write as adjacency matrix, not as list of adjacencies

-A

: same as -a with a space between entries

-l# : specify screen width limit (default 78, 0 means no limit)

This is not currently implemented with -a or -A.

-o# : specify number of first vertex (default is 0).

-d

: write output to satisfy dreadnaut

-c

: write ascii form with minimal line-breaks

-e

: write a list of edges, preceded by the order and the

number of edges

-H

: write in HCP operations research format

-M

: write in Magma format

-m

: write in Mathematica format

-W

: write matrix in Maple format

-L

: (only with -M or -W) write Laplacian rather than adjacency matrix

-S

: (only with -M or -W) write signless Laplacian not adjacency matrix

-b

: write in Bliss format

-G

: write in GRAPE format

-y

: write in dot file format

-Yxxx : extra dotty commands for dot files (arg continues to end of param)

-t

: write upper triangle only (affects -a, -A, -d and default)

-s

: write only the numbers of vertices and edges

-F

: write a form-feed after each graph except the last

-q

: suppress auxiliary output

-a, -A, -c, -d, -M, -W, -H and -e are incompatible.
