A353876 Irregular table read by rows: for each internal vertex of a regular n-gon with all diagonals drawn remove all the edges connected directly to the vertex and then count the number of sides in the polygon that surrounds it; row n gives the number of resulting k-sided polygons, for k>=4, for all internal vertices.
