abstract="The Desarguesian property, an implication of the constant curvature hypothesis was submitted to experimental test. This property requires that, if two vertices of a triangle are joined by segments to the opposite sides, these segments intersect. The results indicate that the property does hold for a significant portion of observers; others may be slightly non-Desarguesian.<p /><p>Language: en</p>",
