Hasse Diagram
A graphical rendering of a Partially Ordered Set displayed via the Cover relation of the PartiallyOrdered Set with an implied upward orientation. A point is drawn for each element of the Poset, and line segments aredrawn between these points according to the following two rules:
- 1. If
in the poset, then the point corresponding to 
appears lower in the drawing than the pointcorresponding to 
. - 2. The line segment between the points corresponding to any two elements and of the poset is included in thedrawing Iff covers or covers .
