... each face boundary of K 4 and changing the parity of the lengths of the paths of J corresponding to the chosen edges. The set of chosen edges of K 4 is a non-empty cocycle of K 4 since the face ... G. If H is a subgraph of the embedded graph, then H ∗ is the subgraph of G ∗ consisting of the dual edges of H. A bond of G is the minimal nonempty edge cut. To each bond o...

... independent computations of the number of Latin squares of order 10. We also give counts of Latin rectangles with up to 10 columns, and estimates of the number of Latin squares of orders up to 15. Mathematics ... subgraph of degree one. A one-factorization of G is a partition of E(G) into one-factors. Clearly, the rows of a Latin rectangle R correspond to the one-factors...

... the members of i S [S] account for at least five of the seven nonempty subsets of S. Without losing generality we may assume that the complement in P(S) − {∅} of i S [S] is a subset of one of the following: (a) ... single member of S.Ifa (unique) member of S is of cardinality 1, then its unique element is considered to be a distin- guished vertex of G. The connectedness of...

... connected. Further, the parity of B  is the parity of A minus the parity of the degree of x plus the parity of the degree of y. Hence B  is an even bond of F and, thus, of G. Note that G<A ∪ B  > ... the parity of B  is just the parity of ∂S minus the parity of ∂V C or minus the sum of the parities of ∂V C 1 and ∂V C 2 , respectively. Hence B  is an even b...
