Publisher: Springer

Using the sphere periodic packings achieved via an fcc lattice or one of its stacking variants 2 , the .. I have been working with issues somewhat tangential to the monster group, and more with the modular forms which are related to the lattice or sphere packing of E_8 and the Leech lattice ?_{24}. Download Sphere Packings, Lattices and Groups. Structure of Factors and Automorphism Groups Masamichi Takesaki.djvu. One may think of a lattice packing, the particular case where the centers of these spheres are exactly the points of a lattice $L$ or, more generally, of periodic packing when the centers of the spheres are finitely many translates $v_1+L,\dots . Symmetric Generation of Groups Robert T. Single contribution in a book: 3. Of interpenetrating sphere packings and one type of interpenetrating layers of spheres. Sphere Packings, Lattices and Groups John Horton Conway, Neil J. Altogether, the lattice complexes with trigonal characteristic space group (with 0, 1, 2 or 3 degrees of freedom) give rise to 225 types of sphere packing.
