TY - GEN A1 - Joswig, Michael A1 - Lutz, Frank H. T1 - One-Point Suspensions and Wreath Products of Polytopes and Spheres N2 - It is known that the suspension of a simplicial complex can be realized with only one additional point. Suitable iterations of this construction generate highly symmetric simplicial complexes with a various interesting combinatorial and topological properties. In particular, infinitely many non-PL spheres as well as contactible simplicial complexes with a vertex-transitive group of automorphisms cab be contained in this way.
