On a family of plane triangulations: combinatorial study, straight-line drawing, and analysis

The combinatorial study of plane triangulations with no separating triangle, called irreducible, gives rise to efficient algorithms for the random generation, optimal encoding and straight-line drawing of these triangulations. Simulations indicate that the grid used by the drawing has with high probability a size close to 11n/27 * 11n/27, where n is the number of vertices. As we will see, this can be proved rigorously using tools from bijective combinatorics as well as analytic combinatorics.
