[mine[:maxe]] [res/mod] [file] Find all bicoloured graphs of a specified class. n1 : the number of vertices in the first class n2 : the number of vertices in the second class mine:maxe : a range for the number of edges #:0 means ’# or more’ except in the case 0:0 res/mod : only generate subset res out of subsets 0..mod-1 file : the name of the output file (defailt stdout)-c: only write connected graphs-z: all the vertices in the second class must have different neighbourhoods-F: the vertices in the second class must have at least two neighbours of degree at least 2-L: there is no vertex in the first class whose removal leaves the vertices in the second class unreachable from each other-Z# : two vertices in the second class may have at most # common nbrs-D# : specify an upper bound for the maximum degree. Example:-D6. You can also give separate maxima for the two parts, for example:-D5:6-d# : specify a lower bound for the minimum degree. Again, you can specify it separately for the two parts:-d1:2-n: use nauty format for output-g: use graph6 format for output (default)-s: use sparse6 format for output-a: use Greechie diagram format for output-u: do not output any graphs, just generate and count them-v: display counts by number of edges to stderr-l: canonically label output graphs (using the 2-part colouring)-q: suppress auxiliary output See program text for much more information.
