Complex:
“Prime tetrahedra and prime octahedra do not have nuclei. In contradistinction to prime tetrahedra and prime octahedra some complex tetrahedra and complex octahedra do have a nucleus. They do not develop structurally in strict conformity to closest packing to contain an internal or nuclear ball until additional closest-packed, uniradius, sphere layers are added. Additional layers require identification as frequency of reoccurrence.”
