       nauty-gentreeg - generate trees


       gentreeg [-D#] [-Z#:#] [-ulps] [-q] n [res/mod] [file]


              Generate (unrooted) trees.

       n      : the number of vertices

              res/mod : only generate subset res out of subsets 0..mod-1

       -D#    : an upper bound for the maximum degree

       -Z#:# : bounds for the diameter

       -s     : use sparse6 output (default)

       -p     : write a parent array

       -l     : write a level array

       -u     : do not output any graphs, just generate and count them

       -q     : suppress auxiliary output

              See program text for much more information.
