	Incidence structure - Wikipedia, the free encyclopedia
		To each incidence structure C we may associate a bipartite graph called Levi graph or incidence graph with a given fl and white vertex coloring where fl vertices correspond to points and white vertices correspond to lines of C and the edges correspond to flags.
		For instance, the Levi graph of the Fano plane is the Heawood graph.
		Since the Heawood graph is connected and vertex-transitive, it follows that there exists an automorphism (such as the one defined by a reflection about the vertical axis in the above figure) interchanging fl and white vertices.

		A balanced polygon, the union of two vertex-disjoint unbalanced polygons, a contrabalanced tight handcuff or theta graph, or a loose edge; here a half edge is treated like an unbalanced loop, so (for instance) a graph consisting of two half edges is a lift circuit.
		The graph whose vertices correspond to the edges of G, and where two vertices are joined whenever the corresponding edges of G are adjacent.

		Graph theory is the branch of mathematics that examines the properties of graphs.
		Informally, a graph is a set of objects called vertices (or nodes) connected by links called edges (or arcs).
		Typically, a graph is depicted as a set of dots (i.e., vertices) connected by lines (i.e., edges).

	Levi graph - Wikipedia, the free encyclopedia
		In combinatorics a Levi graph or incidence graph is a bipartite graph associated with an incidence structure.
		Any geometric incidence structure of points and lines in Euclidean plane such as Desargues configuration gives rise to a (combinatorial) incidence structure.
		The corresponding Levi graph is the generalized Petersen graph G(10,3), also known as the Desargues graph.

	GASC Seminar Talk
		In a natural way, the faces of ranks 1 and 2 in a 4-polytope P provide the vertices of a bipartite graph G. Recently, Asia Weiss and I have examined this construction when P is a finite, abstract regular (or chiral) polytope of Schlafli type {3, q, 3}.
		Indeed, G is then a trivalent semisymmetric graph, so that Aut(G) is transitive on edges but not on vertices.
		After covering some backgound ideas, I'll illustrate the theorems through some beautiful examples: for example, when P is the 4-simplex (which of course can realized as a regular convex polytope), the graph G is the Levi graph for the Desargues configuration.

		At any point during the game, you can use the Graph option to view your inventory and backorder levels, demand received from immediate downstream facility and orders placed to your supplier, and the cost accumulated up to that point in time.
		Note that in this window, you can see the graph only for the facility that you are in charge of and no other facility in the supply chain.
		If you view the Graph window when the simulation is completed, however, you can observe the same information for each of the facilities by selecting a facility from the pull down menu to observe the data for that facility, as shown below.

		A connected simple graph of diameter d is distance-regular if, when we define two vertices to be i th associates if their distance is i, for i =0,..., d, we obtain an association scheme.
		The Levi graph of an incidence structure (also called the incidence graph) is the graph whose vertices are the points and blocks of the structure, with an edge joining a point and a block if and only if they are incident.
		Equivalently, the graph is regular, the number of common neighbours of two adjacent vertices is constant, and the number of common neighbours of two non-adjacent vertices is constant.

		The point of the graph isn’t absolute employment, but change in employment, and if you’re measuring that on this timescale, a range of five or ten million is completely appropriate.
		What would be misleading would be to scale the graph from, say, 50 million to 200 million, when there’s no way on God’s green Earth that January 2004 employment could ever have been anywhere near the top or the bottom of the graph.

		Consistent with a earlier study (Meyer, Gopher and Levi, 1997), graph displays had a clear performance advantage over tables, in both speed and accuracy.
		The advantage of graphs over tables and performance improvement with longer PKR intervals were mainly contributed by higher sensitivity as measured by d’.
		It was also found, that while performance in graphs had a normal distribution, tables showed a bi-modal distribution with a large group of poor performers, and a small group of excellent performers.
