Encoding Lattice Triangulations

We consider triangulations of the n by n integer lattice and describe an encoding that shows that there are no more than O(6.85^(n^2)) of those. Via some other encoding we show that the flip graph of these triangulations is a subgraph of the (3n^2 - 2n) -dimensional hypercube (the dimension is tight). Both encodings described build on a basic idea due to Emile Anclin.

Joint work with J. Matousek and P. Valtr.
