       nauty-multig - generate small multigraphs with given underlying graph


       multig [-q] [-u|-T|-G|-A|-B] [-e#|-e#:#]


              [-m#] [-f#] [-D#|-r#|-l#] [infile [outfile]]

              Read undirected loop-free graphs and replace their edges with multiple

              edges  in  all  possible  ways  (multiplicity  at least 1).  Isomorphic multigraphs
              derived from the same input are suppressed.  If the input graphs are non-isomorphic
              then the output graphs are also.

       -e# | -e#:#
              specify a value or range of the total number of edges counting multiplicities

       -m# maximum edge multiplicity (minimum is 1)

       -D# upper bound on maximum degree

       -r# make regular of specified degree (incompatible with -l, -D, -e)

       -l# make regular multigraphs with multiloops, degree #

              (incompatible with -r, -D, -e)

              Either  -l,  -r, -D, -e or -m with a finite maximum must be given -f# Use the group
              that fixes the first # vertices setwise -T  use a simple text output format (nv  ne
              {v1  v2  mult})  -G   like  -T  but includes group size as third item (if less than

              The group size does not include exchange of isolated vertices.

       -A     write as the upper triangle of an adjacency  matrix,  row  by  row,  including  the
              diagonal, and preceded by the number of vertices

       -B     write  as  an  integer matrix preceded by the number of rows and number of columns,
              where -f determines the number of rows

       -u     no output, just count them

       -q     suppress auxiliary information
