       We hear so much about symmetrical polyhedra. What about their asymmetrical cousins?Here are the two simplest – I think – convex polyhedra that have no symmetry at all, even combinatorially. In other words, they have no non-trivial automorphisms as graphs.Both of them have 7 vertices and 7 faces.https://sketchfab.com/3d-models/asymmetric-heptahedron-1-bc580cf801444bbea24e8f7ac42fb88chttps://sketchfab.com/3d-models/asymmetric-heptahedron-2-0b6db5620b4b486186edbca686dd5bff
