DESCRIPTION

13              Generate all graphs of a specified class.
14
15       n      : the number of vertices
16
17              mine:maxe : a range for the number of edges
18
19              #:0 means '# or more' except in the case 0:0
20
21              res/mod : only generate subset res out of subsets 0..mod-1
22
23       -c     : only write connected graphs
24
25       -C     : only write biconnected graphs
26
27       -t     : only generate triangle-free graphs
28
29       -f     : only generate 4-cycle-free graphs
30
31       -b     : only generate bipartite graphs
32
33              (-t, -f and -b can be used in any combination)
34
35       -m     : save memory at the expense of time (only makes a
36
37              difference in the absence of -b, -t, -f and n <= 28).
38
39       -d#    : a lower bound for the minimum degree
40
41       -D#    : a upper bound for the maximum degree
42
43       -v     : display counts by number of edges
44
45       -l     : canonically label output graphs
46
47       -u     : do not output any graphs, just generate and count them
48
49       -g     : use graph6 output (default)
50
51       -s     : use sparse6 output
52
53       -y     : use the obsolete y-format instead of graph6 format
54
55       -h     : for graph6 or sparse6 format, write a header too
56
57       -q     : suppress auxiliary output (except from -v)
58
59              See program text for much more information.
