Description

nauty-listg - display graphs in a variety of forms

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

[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
	-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.
