It looks at the 24 dimensional Leech lattice in numerous ways. Single contribution in a book: 3. 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 . The paper 'Notes on sphere packings' appeared in 1967 in the Canad. On page 328 of Ernst Witt's Collected Papers Ina Kersten recalls that Witt gave a colloquium talk on January 27, 1970 in Hamburg entitled "Gitter und Mathieu-Gruppen" (Lattices and Mathieu-groups).
