NAME

       nauty-genspecialg - generate special graphs

SYNOPSIS

       genspecialg [-s|-g|-z|-d|-v] [-q] [graph options]... [outfile]

DESCRIPTION

              Generate special graphs.

OPTIONS

   General Options:
       -s : Write in sparse6 format (default)

       -g : Write in graph6 format

       -z : Make digraph versions and write in digraph6 format

       -d : Write in dreadnaut format (can be used with -z)

       -v : For each graph, report the size to stderr

       -q : Suppress summary

   Special Options:
              If  defined, the digraph version is shown in parentheses; # size parameter called n
              in the descriptions.

       -p#    : path (directed path) on n vertices

       -c#    : cycle (directed cycle) on n vertices

       -e#    : empty graph (digraph with loops only) on n vertices

       -k#    : complete graph (with loops) on n vertices

       -b#,#[,#] : complete bipartite graph (directed l->r) on n vertices

              minus a matching of given size if present

       -m#,#... : multipartite graph

       -a#    : antiprism (directed antiprism) on 2n

       -l#    : moebius ladder (directed cycle, undirected rungs) with # vertices

       -D#,# : de Bruijn graph (digraph). D(m,t) has order m^t

       -w#    : wheel with # spokes (directed out from hub)

       -f#    : flower snark on 4n vertices

       -L#    : triangular graph, the linegraph of K_n

       -P#,# : generalized Petersen graph; usual one is -P5,2

       -Q#  -Q#,#
              : hypercube on 2^n vertices. Q(n,t) has vertices  {0,1}^n  and  edges  for  hamming
              distance t.  t=1 is default.

       -A#    : connected antiregular graph on n vertices

       -J#,# : Johnson graph J(n,k), args are n and k

       -K#,# -K#,#,# : Generalized Kneser graph. K(n,k,t) is graph of k-subsets

              of an n-set whose intersection is t. Default for t is 0.

       -C#[,#] : circulant (di)graph; first arg is the number of vertices

       -T#[,#] : theta (di)graph Theta(#,#,...), give path lengths

       -G#[,#] : (directed) grid, use negative values for open directions

       -Y#    : Paley graph or digraph, depending on size. Nondeterministic.

       -X# : produce a named graph, # can be an index or a partial name.

              Use genspecialg --Xhelp for a list.

              Any number of graphs can be generated at once.
