Comment (by ncohen):
> I think that `induced` means slightly different thing in graphs than in
posets. Or that poset just is a different way to see DAG than looking it
as a digraph.
Perhaps. But to make sure that we agree on the meaning: A is an induced
subposet of B if (the transitive closure of A) is an induced subgraph of
(the transitive closure of B).
