Conway characters Sphere Packings Lattices and Groups Grundlehren der mathematischen Wissenschaften We now apply the algorithm above to find the 121 orbits of norm 2 vectors from the known nann 0 vectors and then apply it again to find the 665 orbits of nann 4 vectors from the vectors of nann 0 and 2 The neighbors of a strictly 24 dimensional odd unimodular lattice can be found as follows If a norm 4 vector v E II corresponds to the sum 25 1 of a strictly 24 dimensional odd unimodular lattice A and a dimensional l.

Conway characters Sphere Packings Lattices and Groups Grundlehren der mathematischen Wissenschaften B and an odd unimodular lattice C cf Kne4 An edge is drawn between nodes A and B in Fig 171 for each strictly 24 dimensional unimodular lattice arising in this way Thus there is a one to one correspondence between the strictly 24 dimensional odd unimodular lattices and the edges of our neighborhood graph The 156 lattices are shown in Table 17I Figure I 7 I also shows the corresponding graphs for dimensions 8 and 16.
