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, sparse6 or digraph6 format
              This program does not support incremental sparse6 files; use listg.
              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.
