&lt;&lt;What about considering two half-planes, tiled, and then connect them, have them perpendicular to each other? Would this be a manifold with zero ...

Howard is right. I think we should read the third Smarandache Counter-Projective axiom as follows:<br> "Not every line contains at least two distinct ...

&lt;&lt;Smarandache does something like this in his model. It seems, however, to<br> be better if we can S-deny referring to the same segment. I don't see ...
