As I discovered on CoCalc running Sage 9.1, it appears that any attempt to
use nauty/genbg to build bipartite/hyper-/di- graphs with more than 32
total vertices fails silently.
Please compare the results of:
-
L=list(hypergraphs.nauty(13, 13, uniform=2, regular=2,max_intersection=1))

Suppose I want to generate partitions that are in an arithmetic progression
with a particular step size...seems straightforward enough, so I just set
max_slope and min_slope to that step size. Is this interpretation correct?
Ps=Partitions(11,max_slope=-1, min_slope=-1)
print Ps.cardinality()
