    Packing fraction of body-centered cubic lattice - solid state physics

    Interesting. What happens if the spheres are allowed to have two different sizes? Would it be possible to exceed the FCC density (0.74)?

    Graduate Properties of a volume in 3D Euclidean space

    Then use 'convex'. This includes zero curvature. And doesn't need 'genus 0'.
