SYNOPSIS

DESCRIPTION

13              Find all bicoloured graphs of a specified class.
14
15       n1     : the number of vertices in the first class
16
17       n2     : the number of vertices in the second class
18
19              mine:maxe : a range for the number of edges
20
21              #:0 means '# or more' except in the case 0:0
22
23              res/mod : only generate subset res out of subsets 0..mod-1
24
25              file : the name of the output file (default stdout)
26
27       -c     : only write connected graphs
28
29       -z     : all the vertices in the second class must have
30
31              different neighbourhoods
32
33       -F     : the vertices in the second class must have at least two
34
35              neighbours of degree at least 2
36
37       -L     : there is no vertex in the first class whose removal leaves
38
39              the vertices in the second class unreachable from each other
40
41       -Y#    : two vertices in the second class must have at least  #  common
42              nbrs
43
44       -Z#    :  two  vertices  in the second class must have at most # common
45              nbrs
46
47       -A     : no vertex in the second class has a neighbourhood which is a
48
49              subset of another vertex's neighbourhood in the second class
50
51       -D#    : specify an upper bound for the maximum degree
52
53       Example: -D6.
54              You can also give separate maxima for the
55
56              two parts, for example: -D5:6
57
58       -d#    : specify a lower bound for the minimum degree.
59
60              Again, you can specify it separately for the two parts: -d1:2
61
62       -g     : use graph6 format for output (default)
63
64       -s     : use sparse6 format for output
65
66       -a     : use Greechie diagram format for output
67
68       -u     : do not output any graphs, just generate and count them
69
70       -v     : display counts by number of edges to stderr
71
72       -l     : canonically label output graphs (using the 2-part colouring)
73
74       -q     : suppress auxiliary output
75
76              See program text for much more information.
