	Petersen (Site not responding. Last check: 2007-10-12)
		The Petersen graph is the complement of the Johnson graph J(5,2).
		The Petersen graph is also a cage (graph with smallest possible number of vertices given its valency and girth).
		The Petersen graph is contained in the complement of the Clebsch graph and the Sp(4,2) Generalized Quadrangle and the Hoffman-Singleton graph.

	Petersen biography
		Julius Petersen's father was Jens Petersen, who worked as a dyer, and his mother was Anna Cathrina Petersen who was born in Wiuff.
		Petersen never returned to cryptography; this seems to be another instance of a problem that must have occupied him intensely for a period, until he found a satisfactory solution and moved on to something else.
		Petersen was also a founder member of the Danish Mathematical Society, which came into existence in 1873, and he remained a very active member of the Society.

	Julius Petersen (1839 - 1910)
		Petersen døde i 1910, og derefter fortabte han og hans indsats sig snart i fortidens mørke; hans 100 års fødselsdag i 1939 blev ikke markeret, og i 1947 blev hans grav på Vestre Kirkegård i København sløjfet.
		Petersen blev herefter i 1871 docent ved Den Polytekniske Læreanstalt, i 1879 medlem af Det Kongelige Danske Videnskabernes Selskab, og fra 1887 til 1909 professor ved Københavns Universitet.
		Bing var matematisk direktør for Livrenteanstalten og Petersens gode ven - J.P. Jacobsen omtaler Bing og Petersen som Brandes-tilhængernes Castor og Pollux.

		When August Julius Petersen died a childless widower in 1963, he sought to leave a legacy with his bequest of $65,000 to build a town pool "on the bank of the river I so long travelled."
		Petersen’s will specified the pool be built in his memory at Watson Park, which runs along the river near his former home in East Braintree.
		Martin was just 7 years old when Petersen died at age 93, but he remembers Petersen as a fixture at his family’s holiday gatherings in their South Boston apartment.

		Petersen and his colleague Zeuthen, the two professors at the University of Copenhagen, established a mathematical tradition in Denmark almost out of nothing.
		Both are still remembered for their geometry, but Zeuthen also as a historian of mathematics and Petersen for the graph theory.
		Petersen did pioneering work in several fields, including algebra, combinatorics, cryptography, economics, function theory, geometry, mathematical physics and the teaching of mathematics.

		This graph is interesting for many reasons, one of which is the way it can be constructed from another graph.
		The vertices of the Petersen graph correspond to those edges (of $K_5$), two vertices are connected by an edge in the Petersen graph if the corresponding edges in $K_5$ meet at a vertex (of $K_5$).
		That is, if $v_i$ and $v_j$ are connected by some number of edges in the first graph then $\phi(v_i)$ and $\phi(v_j)$ are connected by the same number of edges in the second.

		Helmut Rehder was born in Hamburg, Germany on June 22, 1905, the youngest son of Julius and Ottilie Rehder.
		He is survived by June, two sons: Helmut Julius of Austin and Christopher of Washington, DC, and five grandchildren, and by his sister Gertrude of Madison, Wisconsin and two brothers who stayed in Germany, Otto and Gerhardt.
		Helmut Rehder may be characterized, as he did his teacher Jaspers, as a humanist concerned with the future of humanity who aimed to interpret the writings of the part under the assumption that they have an active mission to fulfill in the present.

		When the boat was given a sea trial after phase one, it cruised at 20 knots per hour and showed no signs of leaks or structural problems, Lipscomb said.
		Petersen's, which has been in business since at least 1898, has a full-time crew of 15 with specialists in boat building, hand refinishing, mechanics and rigging.

		Theorem 1: Every brick different from K_4 and C_6 and not having the Petersen graph as its underlying simple graph has an edge whose deletion yields a matching covered graph with exactly one brick,with the additional property that the underlying simple graph of that one brick is different from the Petersen graph.
		Theorem 2: If G is any brick whose underlying simple graph is not isomorphic to the Petersen graph, then there is an ear decomposition of G with exactly one double ear.
		Some of the subproblems that emerge are exactly the same as those first studied by James Joseph Sylvester and Julius Petersen in 1889.

		Julius Petersen: the Man, the Myth, the Legend
		Abstract: The emergence of graph theory at the end of the nineteenth century is closely linked to the work of two mathematicians, James Joseph Sylvester in the United States and England and Julius Petersen in Denmark.
		But both his graph theory and some of the other brilliant pieces went unnoticed or met with outright rejection in his own time.This is not to imply that his life was one of disappointment - far from it.
