genus2.npz ... genus6.npz   Triangulated closed surfaces of genus 2 to 6 used by genus(g):
                            the zero set of a smooth union of g tori in a row (marching
                            tetrahedra), simplified by edge contractions that keep the
                            topology. Made by tools/make_meshes.py (vertices V, triangles T).
