nauty-addptg - add additional vertices in various ways

addptg [ -lq ] [ -n# ] [ -j#:# ] [ -e#:# ] [ -ck ] [ -io ] [ infile [ outfile ]]

Add a specified number of new vertices

The output file has a header if and only if the input file does.

	-l	canonically label outputs
	-c	join each new vertex to all the old vertices
	-k	make a clique on the set of new vertices
	-n # the

number of new vertices (default 1)

	-j # -j #:# join a new vertex to # old vertices in all possible ways
	-e # -e #:# use all joins that give the new graphs # edges

( -j , -e are each incompatible with -n )

	-i
			for a digraph, edges go towards the old vertices
	-o		for a digraph, edges go away from the old vertices

( -i is the default if neither -i nor -o is given)

-q
