Draw a 2-dimensional geometric simplicial complex K in the plane which contains at least 10 vertices and at least 4 2-simplices. Pick a 1-simplex in K. It determines a subcomplex L consisting of this 1-simplex and the two vertices , its 0-dimension faces. Now identify the star and the link of this L in K. (The answer can be a clearly labeled picture or lists of simplices that make up the two subcomplexes.)
