Abstract
We define a general class of planar graphs called extended ladders and their corresponding extended ladder links. We then give some of the properties of the extended ladder graphs and corresponding extended ladder links. Finally, we count the number of components of some extended ladder links.
Keywords: Ladder graph, links, knots, component number, planar graph.
