# nauty-listg(1)

display graphs in a variety of forms

## 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.
