Some new properties of the distribution of elements and vertices with respect to the windows of a connected planar graph G are established. It is also shown that a window matrix of G has properties similar to the properties of an incidence matrix of a graph which is not necessarily planar. A method

## Abstract We show that the size of a smallest connected __k__‐regular graph with girth pair (4, 2__l__ + 1) is within a constant of (2__l__ + 1) __k__/2. In so doing we disprove a conjecture of Harary and Kovacs.
## Abstract An application of conservative graphs to topological graph theory is indicated.
## Abstract Coset graphs are a generalization of Cayley graphs. They arise in the construction of graphs and digraphs with transitive automorphism groups. Moreover, the consideration of coset graphs makes it possible to give an algebraic description of regular connected graphs of even degree. In th
