nauty-subdivideg - compute the subdivision graphs of a file of graphs

              Make the subdivision graphs of a file of graphs, or the inverse operation.

       -k#    Subdivide each edge by # new vertices (default 1)

       -i     Perform homeomorphic series reduction For undirected graphs, repeatedly replace x--y--z by x--z if

              x,y are not adjacent and y has no other neighbours.

              For digraphs, repeatedly replace x->y->z by x->z if x,z are

              distinct, x->z is not present, and y has no other neighbours.

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

       -q     Suppress auxiliary information.
