"WebHow close-packed structures of spheres can be constructed: In a first layer the spheres are arranged in a hexagonal pattern, each sphere being surrounded by six others (A). Then a second layer with the same structure is added. But this layer is slightly shifted and hence just filling the gaps of the first layer (B). " - In a multi layered close-packed structure
