DESCRIPTION

12              The g-th generation ancestor of a graph is the graph obtained by
13              removing
14
15              the final g vertices. The 0-th generation ancestor is the  graph
16              itself.  For each input graph, write the ancestors whose genera‐
17              tion is given by the g argument.  No zero-sized graphs are writ‐
18              ten.  Output is always in graph6 format.
19
20              The output file has a header if and only if the input file does.
