I think pp14 would be more enlightening if the pp14.ttl included a disconnected foaf:knows graph, and some triples using another predicate. Something like:

@prefix : <http://example.org/> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .

:a foaf:knows :b .
:b foaf:knows :c .
:d foaf:knows :e .
:f foaf:name "test" .
:a foaf:homepage :h .

Even after Axel's proposed changes I find the wording a bit impenetrable, though admittedly I haven't had time to study the algebra.

Axel, can you tell mw what results you'd expect from pp14.rq with that data?
