It was hot weather here, and that helps :)

That would be good to know. What I also see is that
the output of otter and prover9 is without bindings
e.g. http://www.agfa.com/w3c/euler/graph.out.n3
given http://www.agfa.com/w3c/euler/graph.in.n3
and similarly for E theorem prover
http://www.agfa.com/w3c/euler/graph-proof.tstp
given http://www.agfa.com/w3c/euler/graph.tstp

I could make another attempt to explicitly give
bindings (having an idea via adding instrumentation
premise to the rules but must be careful to keep
the speed of the engine reasonable...)

Right, that's what I also see in our stuff...
