14       -o#    Label  vertices starting at # (default 0).  This can be overrid‐
15              den in the input.
16
17       -n#    Set the initial graph order to #  (no  default).   This  can  be
18              overridden in the input.
19
20       -g     Use graph6 format (default for undirected graphs).
21
22       -z     Use digraph6 format (default for directed graphs).
23
24       -s     Use sparse6 format.
25

31              to:
32
33       n=#    set number of vertices (no default) The = is optional.
34
35       $=#    set label of first vertex (default 0) The = is optional.
36
37       d      indicate graph will be directed
38
39       $$     return origin to initial value (see -o#)

41       ".." and !..\n
42              comments to ignore
43
44       g      specify graph to follow (as dreadnaut format) Can be omitted  if
